John Coltrane is one of jazz"s most influential musicians, but one is hard put to find followers who actually play in his style. Rather, he is influential by example, inspiring musicians to experiment, take chances, and devote themselves to their craft. Interplay, a special 5-CD set highlighting Coltrane"s side-man sessions of the 1950"s, isn"t just a window into his own art, it"s a primer of 1950"s jazz itself.
