Whoa, bro, is there ever gonna be a savage show at Launchpad (618 Central Ave. SW) on Saturday, Dec. 28. It’s, like, all about the jams, brothers and sisters, when the city’s best and most badass Grateful Dead tribute band, Let It Grow, is joined onstage by Morning Mushroom and, for heaven’s sake, freakin’ Pherkad! These three bands will be getting it on with such hep, spaceworthy vibes that you’ll wanna toss your shoes at the ceiling and dance, dance, dance all night! It’s alright; everyone else will be doing it, too. Plus the Launchpad is warm and cozy, so what the hell, it’ll be a dang hippie sock hop! 9pm • $10 presale, $15 at the door • 21+.
