Greatest debut album


Mostly listening to rock music from the 60s and 70s, thus I am asking a biased question. My greatest debut album is From Genesis to Revelation by Genesis.  I understand there were production issues in the making of the album but Gabriel's voice is astonishing on this LP.   I wish I could find a live version of Into the Wilderness but can not. Any help in that would be appreciated.  Look forward to hearing others opinions for selfish reasons as I want to grow my collection and appreciate the opinions represented here.

New York Dolls, The Clash, and the Ramones--all self-titled.

And Television's Marquee Moon.
I would say the Doors debut album The Doors was a Smashing success
and Light my Fire ,one of the all time great songs !!
I think that Barnstorm could technically be called a debut album?  It's listed that way in Wiki and such sites and is considered Joe Walsh's solo debut.  It also fits your favored decade range and it's OK...
