Traffic are a better band than they used to be. And they are going to be even better next time they appear live because Rick Grech will be on bass, giving them more definite rhythm patterns and therefore, more freedom for Steve Winwood and Chris Wood. That's the opinion of drummer Jim Capaldi and he should know. Grech is an obvious extension to Traffic. He was in Blind Faith with Winwood. Capaldi has known him since his Family days, and he, Winwood and Wood were originally involved in Airforce. So, in a way, the album released last week is something of a memorial to the Traffic trio. They won't be appearing for a month or two because of rehearsals so when they next step on stage Traffic will be a quartet.
