Seattle alt-rock supergroup Mad Season weren't around long, but they cemented their legacy with one great album, 1995's 'Above.' On April 2, Sony Legacy releases the three-disc 'Above: Deluxe Edition,' and Diffuser.fm is honored to be giving away a copy. Our one lucky winner also gets a Mad Season T-shirt, which we're guessing pairs nicely with a long-sleeve thermal undershirt or ratty thrift-store cardigan. To enter, just retweet the contest announcement (see the big button below) and follow @diffuserfm and @loudwire on Twitter.

While the prize tee is pretty sweet, the real draw here is the music. Mad Season marked a collaboration between Pearl Jam guitarist Mike McCready, Alice in Chains singer Layne Staley and Screaming Trees drummer Barrett Martin, and several of the 'Above' cuts featured fellow scene giant Mark Lanegan on vocals. In addition to the remastered original album, the 'Deluxe Edition' includes a CD and DVD of the group's final live performance, as well as one previously unreleased tune and three new songs, all of which find Lanegan stepping in for the late Staley and singing over music intended for Mad Season's aborted sophomore effort.

The contest ends at 11:59PM EST on Wednesday, March 20. Click here for a complete list of rules. Good luck!
