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.
