Who would you most like to bring back by resurrection of deceased members or reassembled lineups for just one more album?

My first thought was Zeppelin, but then I thought of how much they covered in their career anyway...they had a good run.
So despite being a bit cleche, I gotta go with Jimi Hendrix. He only had about 4 years, and I liked where he was going with Band of Gypsies. I would've loved to hear a polished album from them.
