Until his death in 2004, soprano saxist Steve Lacy worked with trombonist Roswell Rudd as often as circumstances would permit, from their start together in Dixieland-style bands in the 1950s to the more adventurous styles that both master players are known for. This album of all previously unreleased material with great sound presents work spanning a 40-year period. The majority of this album (nearly 2 hours) is taken from concerts from 1999 and 2002. Additionally there is over 20' of studio recordings. An essential, swinging, free-jazz release.
