Port O'Brien was an American musical group combining elements of acoustic, folk and indie rock, formed in 2005.

They were named after a bay in Alaska featuring a now-abandoned cannery on Kodiak Island where founder member Van Pierszalowski's parents met. They started out as a folk music duo of Cambria Goodwin and Van Pierszalowski while Cambria was living in Cambria, California and Van was living in Oakland. After Cambria moved closer to Oakland they added a rhythm section composed of Caleb Nichols and Joshua Barnhart.

The band toured nationally with artists such as Nada Surf, Bright Eyes and The Cave Singers and toured Europe with Modest Mouse, as well as receiving favourable reviews from Pitchfork Media, Allmusic, and The Times. M. Ward named Port O'Brien his "favorite new band".

The band released three albums; a compilation of self-recorded and early tracks called The Wind and the Swell on American Dust Records and a studio-recorded album All We Could Do Was Sing on City Slang Records, and their latest studio album Threadbare on TBD Records.

I Woke Up Today from the album All We Could Do Was Sing was recently used as the backing music for several Dulux Paints television advertisement in Australia. The band toured Australia in February 2009 as part of the St Jerome's Laneway Festival.

In May 2011 Port O'Brien announced they'd split. Read more on Last.fm. User-contributed text is available under the Creative Commons By-SA License; additional terms may apply.
