Big Band jazz: boon or bane?

Hoo-boy, now that we've got Miles Davis and John Coltrane in the db, have we opened Pandora's box? There are plenty of inroads into the Big Band era now (Coltrane was in the Johnny Hodges Orchestra, Hodges was in the Duke Ellington Orchestra, etc.). I'm foreseeing lots of headaches trying to establish membership in those fluid Big Band lineups.

OK, so now who's going to figure out a way to get the Original Dixieland Jazz Band in the network?

Another terrible, terrible headache is the style of jazz releases. Albums credited to Miles Davis Quintet by our various research sources might actually list just Miles Davis on the cover. Some recordings are credited to entirely different bands when they're reissued years later, and plenty of jazz releases just list the names of the musicians on the cover, even though they may have been recorded by a formally-named band. I foresee a lot of "released by another band"-type releases.
