by Scott YanowThis is an interesting CD, one of many taken from the concerts sponsored by Pablo Records at the 1977 Montreux Jazz Festival. Pianist Oscar Peterson is teamed in an unusual trio with both Ray Brown and Niels Pedersen on basses. Sticking to standards and two blues on the boppish set, Peterson allows both of his sidemen plenty of solo space, permitting listeners to compare the large tone of Brown with the speedy fingers of Pedersen.
