Austin musicians will perform everywhere from H-E-B to Thundercloud Subs to BookPeople on Tuesday as part of HAAM Day, an annual daylong festival to help fund health care coverage for local artists. "It's such a great opportunity to hear so many different local musicians," said Paul Scott, CEO of the Health Alliance for Austin Musicians. HAAM helps Austin musicians enroll in health insurance through the Affordable Care Act Marketplace and helps members pay their premiums. During the festival, musicians will collectively play 120 hours of live music at more than 100 venues, some spread as far as Round Rock and Lockhart.
