Possibly the greatest bluegrass group on the planet will be visiting Humbrews tonight at 8 p.m. when Del McCoury brings his band to our wet, green grasslands ($40). In a half century of playing, McCoury has worked his magic with everyone from the legendary Bill Monroe to contemporary noodlers Phish, all the while maintaining his reputation as the heart, soul and technical master of the genre. As our stars and geniuses grow older and blink out, we must remember to witness them, if only for an evening, so we can carry their music with us to enrich the rest of our lives. This is one such evening.
Two blocks over at the Arcata Theater Lounge, a different set of legends takes the stage at 9 p.m. as Israel Vibration returns to Humboldt County to sing soulful reggae harmonies for a fresh generation's ears while backed by the ever-faithful backing band Roots Radic. Rude Lion opens. ($25).
