We've fallen behind with our free Mp3 of the week in the last few weeks, but we're back now with a catch-up service.

First up, is a live recording of Booker T & the MGs classic instrumental Green Onions, from Aquarium Drunkard. We profiled Aquarium Drunkard last year, and they're still going strong with tons of content that covers great breadths and depths in and across musical genres. If you have trouble downloading the track, try right clicking and selecting "save link as" (Mac users use "control click").

Noise Trade is currently offering the chance to download Bison's debut album Quill. Released late last year, their record has racked up critical praise and the band has been compared to Indie-Folk giants The Decemberists and Mumford and Sons. Grab this opportunity while you can; Quill isn't offered for free download on Amazon, Last.fm or the band's official website, so it may not be available on Noise Trade indefinitely.

Rounding out this three part mp3 omnibus are two free Dizzee Rascal downloads, "Fix Up, Look Sharp" and "Where's Da G's", available via betterPropaganda.

We'll be returning to our regular free Mp3 of the week this Friday, so tune in!
