For me, Ray Benson's Birthday Bash has become SXSW tradition. It's one of my favorite parties every year. Great music, great food and a great cause.
Each year, it is a benefit for HAAM, the Health Alliance for Austin Musicians. If you are an uninsured, professional musician in the Austin-area, you may be eligible for the low-cost primary health care services, basic dental care and mental health counseling that HAAM provides. Get more info here.
