- Dr. Dre tells MTV that performing at a recent concert with Jay-Z and Eminem inspired him to get back to work on his mythically delayed album, "Detox." Says the good doctor, "Being on the stage with Eminem and Jay-Z was one of the most incredible feelings I've felt in a long time. It inspired me, it made me want to hurry up and get back in the studio and put more effort and more work into my own project."

- Reunited grungies Soundgarden will release their new greatest-hits-slash-rarities album, "Telephantasm," via the "Guitar Hero" video game series.

- DMV R&B fans take note: Usher and Sade are both coming to the area. Usher will perform Dec. 12 at the Verizon Center -- tickets go on sale Oct. 8. Sade fans will have to be more patient. She's scheduled to launch her U.S. tour in Baltimore at 1st Mariner Arena on June 16, 2011. Tickets go on sale Oct. 16.
