Last night (31st August) Black Mountain performed on Fallon. They performed the track, "Old Fangs" taken from their soon to be released album Wilderness Heart, which is set to hit record stores on the 14th of September. Make sure to pick up the album when it's out, you definitely won't be disappointed. In the mean time sit back and enjoy the psychedelic vibe they brought to tv sets last night! Thanks to The Audio Perv for the video.
