Cultural Offering has a list of "Perfect Albums". I agree with most of his selections and the ones where I'm not in 100% agreement is only because the album is new to me (but I'll try to rectify that). That said - here's 5 albums I'd suggest adding to the list:
1. Born to Run - Bruce Springsteen
2. Live Bullet - Bob Seger
3. Back in Black - AC/DC
4. London Calling- The Clash
5. Frampton Comes Alive - Peter Frampton
Just missing the cut - The J. Geils Band "Live" Full House and the Grosse Pointe Blank Soundtrack (highly recommended but not sure if soundtracks are allowed).
