David Daniell and Douglas McCombs's first collaborative LP, Sycamore (Thrill 216, 2009), was assembled from seven hours of in-studio improvisations. Daniell and McCombs sifted through the material looking for their favorite moments, then combined, cross faded, mixed, and matched those moments into something that made sense to them as a long player. For their new release, the double LP Versions, they gave the same seven hours of material to noted recording engineer and producer Bundy K. Brown (ex-Tortoise), who was given free rein to assemble an LP of his choosing (subject to approval, of course). The results are fantastic. Brown has chosen to highlight moments in the music that the normally reserved Daniell and McCombs probably would not have chosen. There's a wider dynamic range on Versions, from brutally raw to delicate to practically inaudible. The other interesting aspect is that Brown's selections rarely cross over with the material on Sycamore--this is in no way a ''remix,'' and that is exactly what Daniell and McCombs were hoping for. In addition, Versions includes a second LP of two live performances.
