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 was really taken by the first albums by these bands:

Chicago
Ryan Adams
Elvis Costello
Santana
Have these not been mentioned?
  • Crosby, Stills & Nash
  • Greetings from Asbury Park
  • Ten
Re: Jagged Little Pill, that was Alannis’ American debut album. She had at least one earlier pop album released in Canada, IIRC.
Bellybutton by Jellyfish is a mighty amazing debut. They were incredible live too.
