Some improvisations give us a song-like or a generally pre-structured way of going at it. Others have more pronounced improvisational freedom. The first improv makes me think of Mingus in the best ways. The final piece is mesmeric-cyclic and then a very attractive anthemic theme that reminds one of a Charlie Haden-Carla Bley evergreen in its own way.
Bisio sounds especially inspired by Shawn's open-ended presence, both harmonically-intervalically and melodically. And Shawn in turn seems to delight in the response he gets as it spurs him onward to dig ever more deeply for further musical insights.
It is a magical mix of bold ideas and intensive duo considerations. Anyone with an interest in "serious" music, duo interactions, improvised music, bass and piano performance excellence as it continues to thrive undaunted by the upheavals of recent events, this one is most definitely for you. Highly recommended. A marvel!
