The HA plays Beach-Funk Americana; a blend of sounds old and new with a by-the-sea feel. The band brings the feel of American rock 'n' roll, bonfires on the beach and getting into trouble with friends all together for what they simply refer to as 'Party Music'. HAILING FROM SAN FRANCISCO, CA, THE HA HAS BEEN DEVELOPING THEIR BEACH PARTY SOUND AND FUN-LOVING PERFORMANCES SINCE 2012.

The HA is frontman Brooks Dierker on vocals, harmonica, keys and melodica; Thomas Patrick on guitar; Michael Dyer on drums; Oliver Henrikson on bass.



Since the summer of 2015, the band has hosted a number of ‘Party With Purpose’ events across CA to benefit local non-profits and organizations. In the spring of 2016, The HA was selected for the inaugural artist residency program hosted by Project Amplifi and Smiley’s Schooner Saloon in Bolinas, CA. The residency focused on artist development and community leadership. In the fall of 2016, the band will release their first full length album, Bohemian Howl. In addition to performances at music venues across the greater part of CA and the Southwest, The HA has also played a number of large events, including historic Bay to Breakers, Off the Grid, and various other events across San Francisco and local festivals.




"They are a cool bunch of guys. Mostly originals, some covers... Interactive with the crowd. Could all play their instruments well. Lots of energy. They played straight through the three and a half hours... The girls liked them. They flashed the band a couple times. I like that in a band..."

"Went in to work 2 hours late the next day...It was worth it".

Formerly known as Hopi Astronaut, the band was formed back in 2012 by founding members Brooks Dierker, Michael Dyer, Thomas Patrick and former member Ansgar Lorenz.

Our Story

Our friend’s band from LA was looking for an opening act in SF. Our drummer, who had just taken his first lesson, convinced a few of his drinking buddies they could pull it off and The HA was formed.
