"HAAM Benefit Day is a uniquely Austin event where businesses donate 5% of the day's proceeds to HAAM to support musicians' health. Musicians, most of whom are HAAM members, perform throughout the day at retail stores, outside stages, City Hall and more. The event runs from 6am to well past midnight and community members are invited to shop, eat out, listen to great live music and enjoy! See this year's music schedule." - (From myhaam.org)
