As a gesture to fans that’ve supported them over the past years, Minnesota duo, Atmosphere, dropped a free album on their official website as they gear up for their next official album.

The 13 track offering, titled Strictly Leakage, was leaked recently, via the duo's label, RhymeSayers Entertainment. And for the most part is strictly Atmosphere -- consisting of rapper Slug and producer Ant -- aside from one posse cut featuring Stage One, St. Paul Slim, Muja Messiah, and labelmate Brother Ali, among others, as well as DJ Plain Ol' Bill.

"As a way to thank all of our supporters, Ant and I have put together this party favor," Slug wrote on their website. "It's called Strictly Leakage... thirteen songs to chase away the winter doldrums."

It's offered as a free download, and was leaked before the holidays.

"Is downloadable a word? What's a doldrum?" asked Slug, before wishing everyone the best during the holidays. "Nonetheless, thank you for the love, and please have a happy safe holiday."

Strictly Leakage can be listened and downloaded at Rhymesayers.com. An on-point in-depth review of the release can be read at CraveOnline.

The duo's next album, When Life Gives You Lemons, You Paint That Sh-- Gold, is slated for release on April 22.
