Harold,
They play normally in anything but a computer. What's bad or regretful is that this has detracted from a discussion of some otherwise fine cds. I've listened to the Gordon, Jamal, Blakey and am listening to the Brookmeyer and they're all outstanding. I find the polyrythms in the Blakey cd (the first 3 cuts, the rest is conventional hard bop) fascinating. My family wasn't crazy about that but I loved it. The music is just great and so are the notes. Columbia has done a first class job with these reissues. In each case, the liner notes are written by somebody special. For example, Randy Weston wrote the notes for the Jamal cd.
