Can anyone recommend some exceptional recordings that I may have either overlooked or never heard of for putting speakers to the test? Particularly something with horn section or sax, not symphonic though... either funk, jazz, etc.

I do own several pretty solid CD's and SACD's of Parliament, Isaac Hayes, earlier Stevie Wonder, the Coltrane box set, various Miles, etc....

Are there any exceptional recordings of James Brown out there?

Any suggestions would be most appreciated.
