Berger & Holland were two of the first Europeans to find musical homes for themselves deep in American free jazz, and these improvised duets from 1976 show just how comfortable they were. Berger plays piano, vibraphone & balafon, while Holland plays bass. The compositions are tonal, and as the title insists, it's all about time. It's roots go deep, all the way to Africa, and the overlapping of rhythms suggest the minimalism of Reich, Riley & Glass. Berger's forte is rhythmic dialogue, and the subtle time shifts that are often a music's undercurrent are fore-grounded here.
