Well they've kept this one close to their chests. A previously unreleased studio session recorded by the classic quartet for Impulse on the 6th March 1963 is getting a release on June 29th. In recent years 'new' Coltrane albums have been repackaged material or live recordings which have generally been in circulation among collectors for years. Only one track from this session ('Vilia') has ever been released, and it includes a couple of previously unknown compositions, as well as studio versions of 'One Up, One Down' previously only known from a Feb 1963 radio broadcast from Birdland. Source is Coltrane's copy of the tapes which he apparently gave to his first wife Naima. The official announcement is due later today but looking at some etailer sites which have already posted details it looks like there will be both single CD and vinyl album versions, and deluxe two disc editions with alternate takes (plus digital downloads of course). The deluxe 2CD track listing as given here : CD1 01 Untitled Original 11383 (Take 1) 02 Nature Boy 03 Untitled Original 11386 (Take 1) 04 Vilia (Take 3) 05 Impressions (Take 3) 06 Slow Blues 07 One Up, One Down (Take 1) CD2 01 Vilia (Take 5) - the only previously released track 02 Impressions (Take 1) 03 Impressions (Take 2) 04 Impressions (Take 4) (3:40) 05 Untitled Original 11386 (Take 2) 06 Untitled Original 11386 (Take 5) 07 One Up, One Down (Take 6) Stories in today's Guardian and with a little more background detail the New York Times. Can't wait - *happy dance*.
