Perfect Debute Albums

Dictators-Go Girl Crazy
Nirvana-Bleach
Heartbreakers-L.A.M.F.
the Clash-US version with all the added singles

Foreigner- Foreigner

Moody Blues- Days of Future Passed (they were NOT the same band with Denny Laine, pre Justin Hayward/John Lodge so this IS really their debut album)

Heart- Dreamboat Annie

Boston- Boston (I believe this is the still the #1 debut album of all time in sales)

Kansas- Kansas

Uriah Heep- Very 'eavy....very 'umble

ELO- The Electric Light Orchestra

Photok,

I knew that Bleach was Nirvana's first album, but wasn't Nevermind their first major label debut? I thought Bleach didn't get much distribution until a while after Nevermind. Hence my calling Nevermind a sort-of debut. Maybe I'm wrong. Wouldn't be the first time, sure won't be the last time.

I forgot "Montrose"

Fun thread.
Adding to the list I'd suggest:
Eric Johnson "Ah Via Musicom"
Simply Red "Picturebook"
Julian Lennon "Valotte"
Rolling Stones

I think another worthwhile thread would be, "Best Sophomore Release After a Smash Debut". Seems to me delivering something equal to or better than the initial release - especially after early success - is a real challenge.
