'Saturday night Live' was back this past Saturday and brought in 'The Hangover' star Zach Galifianakis as the host, and Of Monsters and Men was the big musical guest and they totally rocked.

The first song that they performed was their massive hit 'Little Talks'. The band sounded fantastic on the SNL stage, and the signature harmonies that the Icelandic based folk-group brings to the table was all apparent. For their second song of the night was 'Mountain Sound' off their debut studio album 'My head is an Animal'.
