I like both debut albums, but Welcome Oblivion is a cut above for me. Thom is great because he gets all the sounds that we like and puts them together and makes us listen to them for minutes at a time. Trent...the guy can make the most ugly melodies turn into beautiful, seductive, energetic worms that wig all your other thoughts out. And Trent consistently, for the majority of his career, has been able do this. I'm never disappointed with a Radiohead/Atoms for Peace/Thom Yorke song, but again, Thome only makes music that sounds great. Trent turns songs you wouldn't listen to into songs you do listen to. Both great artists/both great bands/both great debuts, but I give an edge to How to Destroy Angels' Welcome Oblivion.
