Series will air on all platforms.

MTV today flipped the switch on a multi-platform extension of its "Discover and Download" series, marrying live TV performances with promotional digital downloads.

The series will air on all MTV channels, including the cable TV channel, the Overdrive Web site and, among others. Digital channels will offer free downloads, exclusive performances interviews, videos, photos and other content.

MTV is extending the program wirelessly as well, with partner Amp’d Mobile. For the next three months, AMP’s users will be able to download free videos of live performance by the Artic Monkeys, Da Backwudz, Flyleaf and Rick Ross.

The original “Discover and Downoad” series appeared on MTV2 last February as a weekly half-hour program.
