Last year on one fateful evening in the UK, Mastodon and Feist happened to be playing the same night on Later... with Jools Holland. Eyes met across the room and rumours began as to the two releasing a split of some kind. Fast forward to the here and now and Tomorrow is a very big day for a lot of music fans. It's Record Store Day. Feist and Mastodon, nicely coined as Fesitdon have now offered up the tracks they are releasing tomorrow via a 7". Mastodon tackle the Metals featuring track "A Commotion" while Feist takes on Mastodon's "Black Tongue" from The Hunter. This is very high on my shopping list for tomorrow!
