Oh No is the second studio album by Chicago rock band OK Go. It was released 30 August 2005. The album was recorded in late 2004 with producer Tore Johansson in Malmö, Sweden and mixed by Dave Sardy in Los Angeles. It is the final album to feature guitarist Andy Duncan, who left shortly after recording finished.
As of January 12, 2007, the album has sold 198,045 units.
After the band's performance at the 2006 MTV Video Music Awards, their album moved up to #2 on the iTunes Music Store album sales charts (as of September 3, 2006). Their album sold 8,250 units in the following week, a 95% increase over the prior week, rocketing from #87 to #69 on the Billboard 200 albums chart, the highest position ever achieved by any OK Go album until the release of Of the Blue Colour of the Sky five years later.
On November 7, 2006, OK Go released a deluxe limited edition CD/DVD of the album. The DVD contains their videos (dancing and playing instruments), a video from 180 fans doing the "A Million Ways" dance for a YouTube contest, previously unseen footage, and a behind-the-scenes look of their treadmill rehearsals for the video and for the VMAs.
