I definitely like some of the earlier musicians you've listed like Bird, Gillespie, Louis and Evans. Also Charlie Christian, Billie Holiday, Lester Young, Johnny Hodges, Stan Getz, some Charlie Mingus and others whose names I don't recall. I don't seem to like things done since the sixties as much. But I must say that Chick Corea can really play the piano. Some of his new Mozart CD with Bobby McFerrin I find really amazing! (I know that this is not jazz, but I think it just shows his virtuosity as a musician.) And of course Wynton Marsalis is a great jazz-classical crossover artist too. I must confess to not knowing very much about jazz. I just hear things that I like.
