Kevin:

By "mainstream" --- I was referring to musicians and bands such as Springsteen and U2. Even though bands like Metallica have had their salad days, I really wouldn't say they are as mainstream as the ones mentioned above.

Granted, Metallica is considered "commercial" among metal acts, but I was thinking more along the lines of CELINE DION and ANDREAS BOCCELLI and KENNY GORLICK (sheesh, no wonder he only uses his last initial!!)

As far as a band like RADIOHEAD is concerned --- in years past, a band of this style would have been confined to a niche market --- they would have played THE CONTENTIAL here in Buffalo, where two three famous Buffalo bands played at one time or another as the house band --- 10,000 MANIACS, GREEN JELL-O (a/k/a - GREEN JELLY, after a successful trademark infringement lawsuit), and the GOO-GOO DOLLS. RADIOHEAD playing a place like this would have punted them into semi-obscurity, marginal noterity, and hence --- NOT MAINSTREAM.

That is what I was thinking --- along those lines.
