It's 4/20 on Saturday, so time for some real talk: Your house is a boring place to be stoned, and Hippie Hill will be crowded and same-y. Of course there is no lack of musicians vying for your reddened eyes, but few events seem as tailor-made to the day's central activity as the Psychedelic Meltdown. It's basically a mini-festival of psychedelic-leaning garage-rock bands, plus a release party for Chicago duo White Mystery, who deals in delirious, skuzzy, basement-friendly hijinx. The lineup is stacked with fun local outfits like Wrong Words, Warm Soda, and Burnt Ones, and the party runs all afternoon and evening with drink specials and rock 'n' roll coloring books. You probably want to get there a little early, though: The music starts right at 4:20.
