About the Line Up


Hey Harriett is an eclectic combination of five young, spirited, Adelaide musicians, united by songwriter and front woman Georgy Rochow. The alternative, indie pop group came to fruition in 2017, producing their debut single Old Parts. Since then, Hey Harriett have gifted the Adelaide music scene their feel-good singles “More” and “Too Fast Too Soon” and full EP, “Nipslip”. Within these, you’ll find fiercely honest vocals pertaining to heartache, mental health, nature and all-round positive vibes. Georgy captivates all with ethereal vocals and rhythmic melodies. The best way to enjoy Hey Harriett’s tunes is to shut your eyes, soak up the warm guitar tones and let your imagination run away as you immerse yourself in their upbeat indie goodness.


SEABASS frontperson Annie Siegmann calls 2020 “the best and worst year of [her] life”, although the band ended the year on a definite high. With the release of energetic single ‘Burn’ a SAM Award win under their belt and a debut EP ready for release, SEABASS certainly didn’t let a pesky global pandemic dampen spirits.

During lockdown, the band got to work on their debut EP ‘Always Kidding’ – a journey into the style and musicianship that SEABASS offers. From chaotic wailing psychedelic guitars to jangly indie rock hooks, the four-piece has all bases covered.

A year on from opening for Grinspoon and the release of second single ‘Brains’, SEABASS are looking forward to their EP launch show at Jive on 27 February 2021. Punters can expect SEABASS’ usual explosive live performance and monster musical prowess, along with some ripping new tunes.


Bitchspawn are a 4-piece rock band hailing from Adelaide Australia. Self-proclaimed beer punkers mainly for their love of beers and writing tunes about the delicious beverage. The band has supported national and international acts such as aussie legends Frenzal Rhomb, Amyl and the Sniffers and Stiff Little Fingers (IRL).


We’ve got a lot to yell about.
