This installment of the Walker's rooftop party is all about music. South Minneapolis oddities experts Dead Media will be setting up listening stations where you can discover deep tracks. They'll also have a variety of books and vinyl for sale. Hipshaker will be on the terrace to spin soul, funk, and R&B from the '60s into the '80s. Brings records for the vinyl swap, try making a gig poster, and take a free cruise through the galleries. Yumi Janairo Roth will also be on hand teaching people the art of sign spinning.
