"Sound of Free" (alternately known as "Settle Down") is a song performed by American musicians Dennis Wilson and Daryl Dragon (the latter credited as "Rumbo") that was written by Wilson and Mike Love. It was released by Stateside Records as a British-exclusive single on December 4, 1970. The B-side was "Lady". In 2013, "Sound of Free" was officially released on CD for the first time on the Beach Boys' box set Made in California. In 2021, a remaster of the song was included on the compilation Feel Flows. A stereo mix was not created because the multitrack tape had been lost.
