Last night, Pearl Jam unveiled "Got Some", a new track from their forthcoming Backspacer album. Conan O'Brien held up the cover art beforehand, which was done by progressive artist/This Modern World creator Tom Tomorrow.

Tom broke the silence on his web site:

So, one of the things I’ve been keeping busy with over the past few months, along with finishing up the children’s book, has been working on some artwork for Pearl Jam. Had to stay quiet about it until now, and I still can’t say too much about it, but I do want to note that the image that Conan held up tonight was only part of a greater whole — it wasn’t the finished album cover. And apart from saying that working with the band has been an utterly fantastic experience, that’s probably most of what I can share at this point.

Backspacer, on track for an autumn release, will be self-released, free of restrictions from a label that might keep Pearl Jam from doing cool things like having Tom Tomorrow do their artwork. Congratulations, Tom!
