Psychedelix Americana

This outside-the-box roots-music fest brings an intriguing mix of sound to Gowanus. The Apr 11 headliner is hokey yet lovable bluegrass-meets-rap fusion crew Gangstagrass, while the Apr 12 bill features veteran Grateful Dead–affiliated country-rock act New Riders of the Purple Sage. See psychedelixamericana.com for the full nightly lineups.
