THEY'RE described as post-punk math-rockers.
But it's definitely not equations that got them where they are: these guys are tight and energetic, and have clearly been jamming together instead of studying.
Sid Air started in 2009, playing all the gigs they could get in Bellingen.
Made up of Rhian Willis on vocals and guitar, Nick Edsall on bass, Jackson Simon on guitar and Marcel Tussie on drums, the four childhood mates hightailed it to Melbourne as soon as they finished school.
There they've been in live music, and it looks like the plan has worked: they've since released an EP, gigged at iconic venues like Sydney's Lansdowne Hotel, and are coming back home for Local M.A.D.E's High on Life! Festival, April 14.
"We're touring the East Coast for our new EP - we've done some home recordings in the past but this is a lot more exciting," drummer Marcel said.
"It's been way too long since we came home to play - it's gonna be good."
