FROM THE NEWS NEST: AB & The Sea cover Katy Perry and more.

San Francisco cuties AB & The Sea (pictured) have made sure that Katy Perry‘s blow up summer jam is just the slightest bit more palatable… or at least more guilt-free when it gets stuck in your head. We like all of the soft edges of the cover, as well as how the boys make it such a sweet tribute. Get a free Mp3 here: A B & The Sea “California Gurls”.

After a not-so-awesome show this weekend at the HARD FEST in NYC, M.I.A. had promised her fans that went a free show when things go a little bit more her away.

Yeah Yeah Yeahs fans, you’ll be all over this deliciousness: the band has released a concert film called Live in London, which is now making the rounds on iTunes. The 80-minute film was taken at their December 1, 2009 show at the 02 Academy in Brixton. It makes waiting for a new YYY album almost easier.
