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.

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...
The Fleetwood Mac - Fleetwood Mac album as it is the first of many great offerings of the legendary iteration of this group.  BTW...the 2018 CD remaster is fantastic!!  Listening to it right now.😀
