Oh Hiroshima

Oh Hiroshima is a Swedish post-rock band, founded in 2009 in Kristinehamn by Leif Eliasson and Jakob Hemström, who were later joined by Simon Axelsson and Hemström's younger brother Oskar Nilsson. The band is noted for its subdued electronic instrumentation, abstract guitar texturing, and use of vocal soundscapes.

Beginning as an experimental music project between Eliasson and Hemström, Nilsson officially joined the group as their drummer in 2011 during the writing process for debut album Resistance Is Futile, having before recorded bass with the group. Axelsson joined the band that same year as their bass player.
