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.

@slaw, I beat you to The Traveling Wilburys! I left off the Little Village album (weak material imo. But they were one of the best live bands I've ever seen & heard. Ry Cooder is God ;-), but could have and should have listed that band's true debut album, John Hiatt's Bring The Family. Fantastic!

OK, Why was there any other posts forthcoming? in the way you found to post?
I suspect there might be a little bit of confusion over what was meant by greatest debut album in the OP. 😳 I interpret it to mean the most auspicious debut album. Or perhaps the most historically significant. So, in that light I would add Elvis Presley but not Bing Crosby, even though the guy sold a lot of records.
