Grandmaster Flash will host a new weekly mix show, called Flash Mash on SIRIUS' Boombox channel 61. Flash Mash will air every Saturday from 6 to 9pm ET starting April 16th.

"I'm using the same template for this new show that I used in 1971, before hip-hop started - a combination of pop, rock, jazz, blues and R&B," said Flash. "I'll be talking about the use of samples, what certain songs mean and where they came from, and playing what I feel," he added. "I'm calling out to all the labels throughout the world to send me their stuff, because this is going to be an amazing mix."

Moby, electronica superstar and close personal friend of Eminem, will give a live performance at the W Hotel in LA, which will be broadcast on SIRIUS Satellite Radio on April 4 from 7pm to 9pm.

Moby's performance will be broadcast exclusively on Chill SIRIUS CH 64 (ambient, electronica and downtempo rock).

The W Hotel features Sirius Suites at the W Times Square and W Los Angeles, providing guests access to SIRIUS Satellite Radio. SIRIUS will also air Moby in-concert on April 22nd, which will of course feature selections from his double-CD named, amazingly enough... Hotel.

Oh, and since we're on the Hotel kick, check out Moby Hotel just for shits and giggles.
