Jimi Hendrix - The Ultimate Experience
Alice in Chains - Dirt
Black Sabbath - Paranoid
Pink Floyd - Dark Side of the Moon
Nirvana - Nevermind

Yes, all commercially successful, but also reminiscent of other times when the mainstream wasn't so overcome with tunnel-vision for mindless dreck.

Great Choices!!!

But I would have switched Alice in chains with something by The Clash, Sex Pistols or even The Ramones

Just throw a bunch of best ofs and Greatest hits albums at them.
Mothership - Zeppelin
Best of Both Worlds - Van Halen
Devil's got a New Disguise - Aerosmith
Greatest Hits Vol. 1 - Korn
Lest We Forget - Marilyn Manson

then:
Back in Black - AC/DC
and
Metallica (the black album)
