It's a fully three-way trio session with the loquacious Oluyemi Thomas on bass clarinet, soprano, musette, etc., and Michael Wimberly on drums, recorded live in NYC's Brecht Forum in 2008.
What we have, simply, is excellent free trio music. Sirone alternates between the percussive attack for which he is known and a free unfolding of melodic-textural ideas. Thomas plays good snaky bass clarinet and impassioned reeds in general while Michael Wimberly plies a very dynamic and very musically phrased set of drums.
It's a fitting farewell to Mr. Sirone, doing what he did so well in the company of two very articulate free masters. This release is available in limited edition as a CD or LP.
