Artist Dinos Chapman is releasing his first record, of electronic music. Luftbobler is described as "schlampige musik", which translates roughly to "sloppy music", or (as one reader points out on Twitter "slutty music"). Chapman has been playing with sound for the last ten years, and made this 13 track record in his basement in East London. As part of the release The Vinyl Factory will also host an installation from 27 February–4 March next year (more details incoming). 

Luftbobler is released on 25 February via The Vinyl Factory on vinyl, CD and digital. A limited version of the artwork will include a hand coloured etching. More details incoming here.     

A bootleg cassette of an Anthony Braxton concert from 1972, recorded on two tiny microphones taped to the arms of a pair of large sunglasses, has been unearthed. The glasses pictured above belonged to the bootlegger in question (although they may not have been the actual set used to record this concert), and were shown to Braxton's Tri-Centric Foundation earlier this year as part of the tape handover.

The solo concert took place at Carnegie Recital Hall on 10 June 1972 when Braxton was 27, and this is the only known recording. The tape, which contains around 40 minutes of material, has been converted to digital and is in the process of being mastered. The Tri-Centric Foundation says it plans to release the recording, although it has no solid dates as of yet. Listen to an unmastered clip of "Lush Life" from the recording above.

New York based Peruvian sound artist Maria Chavez is publishing a book of essays and illustrations on turntablism, titled Of Technique: Chance Procedures On Turntable. The book is intended to work as a 'how to' manual with illustrations that are meant to be torn out and used as diagrams for learning to create different sounds and hand movements. 

For her experimental turntablism, Chavez uses new and broken needles (the latter of which she refers to as 'perfect to ruin' needles), on a collection of vinyl she uses to build a sound palette.

Chavez has been an artist in residence at Issue Project Room, among other places, and played in Christian Marclay's Screenplay at the Whitney Museum in 2010. 

Of Technique: Chance Procedures On Turntable is published by Printed Matter. More details here.  

On 23 November Oxford's Pitt Rivers Museum hosts its Christmas Light Night: a series of performances and installations using the museum's digitised sound archive, put together by composer in residence Nathaniel Mann and ethnomusicologist Noel Lobley. 

The night will include a performance by sound artist Robin Alderton, who will be performing surrounded by dictaphones, Dansette players and reel to reel playing material drawn from the archives, manipulating these field recordings and the mechanical sounds of the machines. 

The night also includes Father Damian Webb's recordings of children's songs from Europe and East Africa, played in a tent on the lawn outside, and sounds from the archive of American author Louis Sarno recorded in the Central African Republic in the 1980s, which will be played into darkened galleries and visitors will be given torches to explore.  

Oxford Pitt Rivers Museum, 23 November, 6–10pm, free. More details here. 

On 10 December Grime collective Ruff Sqwad are releasing a collection of 22 instrumentals. The compilation, White Label Classics, is out via No Hats No Hoods on CD and digitally (the CD release includes "Lonely People" and "Died In Your Arms", and in their place the digital release carries "No Bass" and "Cleo Remix").  

The instrumentals were culled from around 50 rarities by the East London crew ("These are the anthems, the tunes people remember us by," reads the release), which included Tinchy Stryder plus producers Dirty Danger and Rapid. White Label Classics comes with a 16 page booklet that includes photographs and interviews with Rapid and Dirty. More details including the full tracklisting here. 

INA-GRM is releasing a box set of acousmatic composer François Bayle recordings, covering 50 years spread across 15 CDs. 

Bayle joined the Group de Recherches Musicales (GRM) in the early 1960s and became its director in 1975. One of his major works was the Acousmonium – an orchestra of over 80 loudspeakers. Bayle trained with Oliver Messiaen, Karlheinz Stockhausen, and Pierre Schaeffer. He also founded French TV and radio archive Institut National de L' Audiovisuel with Ivo Malec and JC Eloy. His aim was for the listener to feel the motion and vibration of energy in the universe.  

More details on the release at INA-GRM site.  

Dropped in our inboxes today: news that Dean Blunt & Inga Copeland (aka Hype Williams) are apparently starting an imprint called World Music Group. Scant details as per usual, but a brief missive states: "Most future recordings/works will be issued or licensed through this channel."

Jazz trumpeter Ted Curson has died of heart failure age 77. 

Curson played on over 500 records as a sideman, and was leader on 18. He was influenced by Clifford Brown and Johnny Splawn, and encouraged by Miles Davis, he moved to New York in 1956. There he played with Red Garland, Vera Auer, and Cecil Taylor before joining Mingus's group for two years, where he played on Pre-Bird and Charles Mingus Presents Charles Mingus, among others. He left the group to lead a quartet with saxophonist Bill Barron and play freelance.

Notably, Curson contributed to the soundtrack for Pier Paolo Pasolini's Teorama, (the title track from Tears For Dolphy on which he was leader), although he was not credited, and it took a long legal wrangle for him to receive payment.

After the dissolution of his quartet Curson moved to Denmark, but moved back to New York in 1983 for a ten year contract to play in jam sessions at the Blue Note six nights a week. He told Brian Priestley in 1984: "Europe for me is like coming home, because I can do everything I want to do." He became heavily involved in running the Pori Jazz Festival in Finland, and was awarded the key to the city in 1988.
