"Rollercoaster" is the third single from Black Mountain's Wilderness Heart. This song really showcases the band's trademark psych-metal sound, and throughout it the interchanging vocals of Steve McBean and Amber Webber are in full force. The song was recorded at Sunset Sound in Hollywood with D. Sardy. The b-side to this single is entitled "In The Drones" and is previously unreleased. It features Webber's haunting vocals at the forefront, accompanied by reverb-drenched picking and shadowy synth stylings underneath. The song was recorded in Seattle at London Bridge Studio with Randall Dunn.
