FREE MUSIC TECH BETA INVITE WEEK continues on Hypebot with startups sharing beta invites each day.  Yesterday, Serendip kicked things off and there are still invites available for what The Next Web called "the smartest music integration to Twitter that I’ve seen". Today, Mobile Backstage for Facebook joins in the fun, offering free beta invites to Hypebot readers.

Mobile Backstage has been employed by all four major label groups and numerous independents for artists such as Lykke Li, You Me At Six, and Black Label Society and the new Facebook option brings the same utility to engage, mobilize and monetize any artist's virtual tribe of fans: Artists joining the free beta can upgrade to the paid mobile platform at any time. 

Get your free Mobile Backstage for Facebook beta invite here.
