Rethinking live electronic music: a DJ perspective
No full textThe author critiques the conventional understanding of live electronic music through empirical research on his own DJ practice and investigates others working in the field. In reviewing the opinions of theorists and practitioners in both the live electronic music genre and DJ-ing he argues against the body/machine dialectic that has determined much of the thinking in the former. The author forms a notion of the DJ as a real-time composer working beyond traditional binary distinctions who brings the human body and machine into a mutual relationship. Through practice-led research he charts an investigation beginning in physical human gesture and culminating in digital machine repetition. He concludes that mechanical and digital repetition do not obscure human agency in the production of live works and that this concern is imaginary

No full texthpDJ: An automated DJ with floorshow feedback
No full textMany radio stations and nightclubs employ Disk-Jockeys (DJs) to provide a continuous uninterrupted stream or “mix” of dance music, built from a sequence of individual song-tracks. In the last decade, commercial pre-recorded compilation CDs of DJ mixes have become a growth market. DJs exercise skill in deciding an appropriate sequence of tracks and in mixing 'seamlessly' from one track to the next. Online access to large-scale archives of digitized music via automated music information retrieval systems offers users the possibility of discovering many songs they like, but the majority of consumers are unlikely to want to learn the DJ skills of sequencing and mixing. This paper describes hpDJ, an automatic method by which compilations of dance-music can be sequenced and seamlessly mixed by computer, with minimal user involvement. The user may specify a selection of tracks, and may give a qualitative indication of the type of mix required. The resultant mix can be presented as a continuous single digital audio file, whether for burning to CD, or for play-out from a personal playback device such as an iPod, or for play-out to rooms full of dancers in a nightclub. Results from an early version of this system have been tested on an audience of patrons in a London nightclub, with very favourable results. Subsequent to that experiment, we designed technologies which allow the hpDJ system to monitor the responses of crowds of dancers/listeners, so that hpDJ can dynamically react to those responses from the crowd. The initial intention was that hpDJ would monitor the crowd’s reaction to the song-track currently being played, and use that response to guide its selection of subsequent song-tracks tracks in the mix. In that version, it’s assumed that all the song-tracks existed in some archive or library of pre-recorded files. However, once reliable crowd-monitoring technology is available, it becomes possible to use the crowd-response data to dynamically “remix” existing song-tracks (i.e, alter the track in some way, tailoring it to the response of the crowd) and even to dynamically “compose” new song-tracks suited to that crowd. Thus, the music played by hpDJ to any particular crowd of listeners on any particular night becomes a direct function of that particular crowd’s particular responses on that particular night. On a different night, the same crowd of people might react in a different way, leading hpDJ to create different music. Thus, the music composed and played by hpDJ could be viewed as an “emergent” property of the dynamic interaction between the computer system and the crowd, and the crowd could then be viewed as having collectively collaborated on composing the music that was played on that night. This en masse collective composition raises some interesting legal issues regarding the ownership of the composition (i.e.: who, exactly, is the author of the work?), but revenue-generating businesses can nevertheless plausibly be built from such technologies
Characterisation of DJ1 (PARK7) in human brain: possible involvement in idiopathic Parkinson's disease and other neurodegenerative disorders
No full textMutations in the DJ‐1 gene can induce the development of early‐onset Parkinson's disease
(PD) through a loss of protein function. Currently any possible role for DJ‐1 in sporadic PD
remains undetermined. To address this, we have studied the characteristics and activities of
DJ‐1 in post‐mortem human brain tissue in order to gain insights into its contribution to the
development of PD and other neurodegenerative disorders.
Western blotting revealed DJ‐1 protein expression to be reduced in several brain regions
associated with PD pathology including nigra, striatum and frontal cortex. Similarly levels of
DJ‐1 mRNA were also shown to also be lower in PD striatum and frontal cortex suggesting a
transcriptional regulation of protein expression in human brain. Further analysis of DJ‐1
gene expression showed PD related changes to be variable throughout the brain, with
regions like the amygdala and entorhinal cortex displaying an up‐regulation. DJ‐1 protein
was also shown to undergo increased oxidation in PD cases, highlighting the elevated
oxidative stress conditions in PD. By using immunoprecipitation to investigate a possible role for DJ‐1 as an in vivo regulator
of translation, we found DJ‐1 protein associates with RNA transcripts for selenoproteins,
PTEN/Akt pathway components and mitochondrial subunits of complex 1. Protein levels for
a number of these transcripts were altered in PD tissue without any parallel change in
mRNA levels. DJ‐1 is reportedly involved in a diverse range of cellular activities and its
proclivity to associate with multiple RNA species provides a simple biochemical mechanism
for this. Moreover it demonstrates that under conditions of elevated oxidative stress, DJ‐1
can instigate a rapid and compartmentalised up‐regulation of pro‐survival proteins in a
transcriptionally independent manner.
Analysis of DJ‐1 in tauopathies showed co‐localisation with 3R and 4R tau, implicating a
possible chaperone function for DJ‐1. Unlike in PD, no altered expression of DJ‐1 mRNA and
protein was observed

No full textInterview of author Phenderson Dj\ue8l\ued Clark at the Zora Neale Hurston Festival in Eatonville, Florida
No full textAward winning author and founding member of FIYAH Literary Magazine, Phenderson Dj\ue8l\ued Clark, is interviewed by Grace Chun, project coordinator at University of Florida Samuel Proctor Oral History Program, as part of the 2020 Zora Neale Hurston Festival in Eatonville, Florida. Mr. Clark shares how his time in Trinidad, his exposure to afro-creole folktales, Hindu stories, Muslim festivals as well as his exposure to Twilight Zone and old horror movies from his parents nurtured a deep interest in the fantastic. Mr. Clark defines afrofuturism as something to do with the future, whether it is how Black people will exist in the future or futuristic ideas. He describes how his writing fits more with retro-afrofuturism, where you imbue the past with future elements and explore a past that never was. Mr. Clark says that afrofuturism offers a way to resist the kind of future in a world like now and how to form a resistance against it; it empowers people to imagine a different future, a possibility of a different future. He also talks about how afrofuturism extends beyond literary work into music and other creative forms
