Oslo is an alternative/indie rock band based in California. They have existed together as a trio, with a core of Mattia Borrani on lead vocals, Kerry Wayne James on bass, and Gabrial McNair on guitars. Famously, McNair was a touring member of the band No Doubt.
They have since added keyboardist Damon Ramirez and went through twelve drummers, settling on original drummer Charlie Walker, who initially left the band to live in New York City. They released their second album, The Rise and Fall of Love and Hate, in November 2007.
Their third album, "High Mountain Sessions Vol. 1" was released in 2011. The seven track album was mastered in San Francisco.
In December 2016, the trio released a five song EP, "The Morning After." On April 9, 2017, they opened for Dreamcar, the band featuring members of No Doubt and AFI lead singer Davey Havok, at the Great American Music Hall in San Francisco. During the gig, they joked that they were working with their 13th drummer Lyle Riddle
