Renowned pianist and composer Burton Greene joins French composer and improvising guitarist Guillaume Gargaud performing on acoustic guitar, for four duo improvisations recorded at Tilo's Ark, in Weesp, The Netherlands in 2019, in crisp & often rapid dialog that uses space and reflective moments well, the duo joined by Tilo Baumheier on flute for three pieces.

New York free jazz pianist Burton Greene and free jazz vocalist Silke Rollig recorded these thirteen improvisations at The Loft in Koln, Germany in 2013, a mix of lyrical free playing with scat and freeform vocals, accompanied by flute, and by sax, on one piece each.
