It's part Prince, part Beach Boys, part Lynyrd Skynyrd, and all My Morning Jacket in their poppy jam band glory.  "Evil Urges" is the title track to their new LP out in June (above is the album art work).  The new album itself is a brilliant change of pace towards more disco grooves, a logical shift considering the groups dub/reggae vibes felt on their breakthrough album, Z. 

Of course, MMJ offers the free track reluctantly.  From their website:

gall durn it -- we're just old fashioned that way. sometimes... gentle reader, in this age of instant gratification, waiting can be so rewarding, it can teach us a valuable lesson about the triumph of the human spirit... but sometimes, like our old friend tom petty said- waiting is the hardest part. thank you all for being so supportive of us, and unending in your love... from the bottom of our cold dead hearts!
