It’s rare to hear a newish indie band say they’re based in San Francisco anymore. Much like what’s happened to Austin in the last 10 years, the tech boom of that last two decades pushed out many artists and others who couldn’t afford the skyrocketing cost to live in the city by the bay. But that hasn’t stopped the dudes in Hot Flash Heat Wave from hunkering down and continuing to write their psych-ish doo-wop-like indie rock. Since 2015, Adam, Ted, Nathaniel and Nick have been pumping out shimmering waves of rainbow colored dream pop perfect for a summer day at South Padre Island.
