I know there probably aren't a lot of hip-hop fans here, but I thought it was worth posting anyway. Nate Dogg was T-Pain before there was T-Pain but without any of the gimmickry or computer tricks. Just a fantastic voice. The list of R&B singers and rappers who featured him on at least one of their songs is a who's who of R&B and hip-hop. He had a great voice, and he helped make a lot of fun songs.
The article points out that he was a former marine, a multiple time Grammy nominee, and an unfortunate multiple stroke victim. I don't think I saw cause of death or suspected cause of death, but I guess he wasn't in the best of health. Very sad.
Sorry. I don't have a lot of words for this one. Lou Reed, Velvet Underground Leader and Rock Pioneer, Dead at 71 (rollingstone.com) Edit: My favorite rendition of Sweet Jane. This really has bummed me out.
