The members of Arbes are Sam, Jess, and Anita. I think Jess is doing the singing and playing the bass, Sam is on guitar, and Anita is on the kit. The sound here is something special and it recalls disparate bands -- a hint of Bettie Serveert here, a 4AD-worthy guitar-line there -- but the overall effect is one of something fresh and special.
"Beach Side" is from the band's recent Swimmer EP and I urge you to get your hands and ears on that one. In the meantime, follow Arbes on their official Facebook page.
