In November 1964, a number of New York musicians (including Sun Ra) formally banded together as the Jazz Composers Guild. Under JCG sponsorship, the series “Four Days in December” ran from December 28 through 31 at Judson Hall. Sun Ra and his Arkestra appeared on the 31st, along with the New York Art Quartet. All of the music from the Four Days in December series was recorded by the JCG for its own label; a December 1964 announcement in Down Beat indicates that a sampler LP was planned as the first release. However, the Guild broke apart early in 1965, so this never came to pass. Later there were plans (again abortive) to issue the concerts on the Fontana label. Almost a dozen years later (1976), Sun Ra issued the LP "Featuring Pharoah Sanders and Black Harold" [comprised of tracks 6–11 of this digital edition].
In 2013, David Byrne’s Luaka Bop label released Who is William Onyeabor?, a compilation of the obscure, but increasingly influential Nigerian musician William Onyeabor. Now (in 2014) follows a 9xCD box set that collects the entirety of Onyeabor’s recorded output.
