According to the sleeve, this album was recorded by bassist and composer Barry Guy, founder of the London Jazz Composers Orchestra and the Barry Guy New Orchestra, and the versatile Norwegian saxophonist Torben Snekkestad, a member of the Copenhagen Saxophone Quartet. But it sounds, at moments, like a dialogue between birds, at others, an altercation between elephants. This is a thoroughly good thing. Recorded over two days in Copenhagen in 2011, the album, by turns beautiful and abrasive, represents a highly successful meeting of musical minds. For just two musicians, it is startling just how much music they make, exploring a great diversity of textures and sounds. Brimming with imagination, Slip Slide and Collide convincingly makes the case for improv as spontaneous composition. Although the tracks take their names from islands, there is no sense of insularity here, the two musicians slipping, sliding and colliding until their instruments are at times indistinguishable.
