Honkin' on Bobo is the 14th studio album by American rock band Aerosmith, released on March 30, 2004 by Columbia Records. The album includes 11 covers and one original track titled "The Grind". The sound reflects Aerosmith's blues-based influences and showcases a rawer sound (reminiscent of their 1970s heyday) compared to their recent commercial efforts and was also produced by Jack Douglas, who was Aerosmith's producer on a vast majority of their 1970s' output. The album sold over 160,000 copies in its first week, reaching #5 on the Billboard 200. Honkin' on Bobo was certified gold by the Recording Industry Association of America on May 11, 2004.
