This band came together for this one-off concert at the Detroit Jazz Festival in 2017, and the opening track, ‘Someplace Called Where,’ sounds like it. The quartet feel their way into the music and – to use a term Esperanza Spalding uses in the liner notes – they are ‘building the plane while flying it’. This is spontaneous interaction, but not at the level of his quartet with Danilo Perez, Brian Blade and Jon Patitucci, and the composition ‘The Stuff That Dreams Are Made Of (A Conversation)’ is indeed a conversation built around Shorter’s soprano sax and Genovese’s piano, Shorter in solo, then in duet, before giving way to Spalding’s vocal and more searching, Genovese’s piano interacting with Spalding, with interventions by Shorter.

‘Endangered Species’ follows a similar trajectory for 21 minutes, with no clear idea of the destination – interaction leads to solo episodes which seem to peter out and give way to more solo episodes. Carrington seems to pick broken rhythmic patterns, leading to musical progress like participants in a three-legged race, and no one gets to sprint to the finish line.
