Half of this LP contains the famous session on which Sonny Rollins teamed up with his idol, the great tenor Coleman Hawkins. Actually, the competitive Rollins did everything he could during these performances to throw Hawk off with plenty of sound explorations and free playing, but Hawkins keeps from getting lost and battles Rollins for a tie; pianist Paul Bley plays well too. The remainder of this LP (three selections apiece from the former LPs Now's the Time and The Standard Sonny Rollins) is more conventional but has its moments of interest. The young Herbie Hancock is on piano for all of these tracks and guitarist Jim Hall helps on "Trav'lin Light." Rollins's RCA recordings of the '60s are all worth picking up.
