by Scott Yanow This is a fairly typical date from the Oscar Peterson Trio (which features the pianist-leader, bassist Ray Brown and drummer Ed Thigpen). Many of the songs on this LP are associated with other musicians (such as "Waltz for Debbie," "This Could Be the Start of Something Big" and "Six and Four") but Peterson has little difficulty swinging them in his usual fashion; a highlight is the original version of Ray Brown's "Gravy Waltz." [A Japanese version of Affinity was released in 2004 and includes bonus tracks.]
