Dave Nattress… OK another question, from me this time, I don’t think it’s been done already, but apologies if it has. What about the best rated debut album? I think of a few that really blew me away. For instance Black Sabbath’s first, Scouting for Girls – wonderful songs all of them and brilliant arrangements, Hopes and Fears – Keane.
Phil Gill…Jeff Buckley “Grace” wins this hands down.
Tony Ham… The Stranglers, Rattus Norvegicus, my all time favourite album.
Tony Davis… How about Jethro Tull This Was
Patrick Lewis… Fleet Foxes
Glenn Piper… Bridge of Sighs-Robin Trower 
😀 Black Sabbath -Black Sabbath
Colin Fox… Can’t buy a thrill.
Phil Gill… A Girl Called Eddy
Roger Dando… Boston. Led Zep 1.
Michael Wilson… The Damned “Damned Damned Damned “. I saw them at the Dome Brighton on thier 40th tour. A great night had by all.
Tony Ham… Saw them last year on the 40th anniversary tour, they played the album right through. Same one I went to. Seeing them in Bexhill next year.
Kev Towner… Queen – Queen
Martyn Baker… Osmonds
Dave Valentine…The Velvet Underground and Nico. Not just the greatest debut of all time, probably the greatest album of all time.
Nigel Sherwood… Please please me , always my favorite Beatles album
Tony Qunta… Are You Experienced!
Will Cornell… A vote for John Prine’s first. More genius songwriting in any 10 seconds of any of those songs than we’d see in the next 40+ years, and he had some heavy competition!
Mike Curtis… Can I have two? Led Zeppelin 1 and Crosby Stills & Nash.
Paul Morfey… Dire Straits!!
Steve Reents… Van Halen’s first album is up there.
Chris Meachen… Free,- Tons of sobs..
Pete Prescott… Montrose, Rickie Lee Jones, Nick Drake Five leaves left, Santana Sep 1, Free Tons of sobs
Pete Fisher… Taste
Patrick Lewis… Pentangle
Steve Kinch… Not sure if this qualifies as the best debut album, but 21st Century Schizoid Man by King Crimson has got to be the best opening track on a debut album. The sheer fearlessness and confidence of that track is progtastic 
Clifford Rose… Led Zeppelin’s first album.
Peter Thomson… Debut’s Greatest Hits?
Andy Qunta… Are You Experienced! I expect nobody else suggested this one!
Dave Nattress… Well the first King Crimson album with 21st Century Schizoid Man on (as Steve Kinch commented) was pretty out there. I have it on CD never having got the vinyl which a good friend had back whenever. At the time, listening to that and name-dropping King Crimson we thought we were pretty cool – to walk around with that cover under your arm we thought was pretty cool also. I was delighted and surprised to hear the track on R2 on a saturday morning programme about 2 weeks back.
