Last night, Melissa Etheridge helped launch Hard Rock's Pinktober campaign for breast cancer awareness at HRC Hollywood Blvd. Joined by up-and-coming singer Crystal Bowersox, Melissa tore through a set filled with hits past and present, lending her voice and her talent to a great cause. This is the fourth year that Melissa has served as Hard Rock's Artist Ambassador for Pinktober, putting her clout and influence behind a cause very close to her.

Helping to launch Pinktober into its 11th year(!), Crystal Bowersox, the America Idol season 9 runner-up, warmed up the crowd with her sprawling, crystal clear voice and her flair for performance. She definitely earned her keep last night. Here's a great pic of Crystal and Melissa showing everyone how it's done. That is, from the soul, from the heart:

We just wanted to thank Melissa Etheridge for again lending her time, her talent, and her voice to Pinktober, an initiative that we hold dear. We also wanted to thank everyone who attended the show last night, as well as the all the Hard Rock fans the world over who've helped us donate millions to the cause over the years. We couldn't have done it without you all. Thank you!
