Since 1995, Jefre Cantu-Ledesma has been a fixture in the experimental music community, both as a member of improvisational post-rock group Tarental and founder of eminent ambient/drone label Root Strata. Under his own name, Cantu-Ledesma releases calming compositions of shimmering synths that play languidly, delayed keys rippling out atop placid pools. Delicate strains of broken melodies trickle down warm wallpaper drones swelling with reverb. Check out the video for Difficult Loves off his latest release Devotion, then listen to his piece for SFMOMA below.
