Meltdown is the fourth studio album to be recorded by the Northern Irish rock band Ash. The album was released on 17 May 2004 through Infectious Records and Home Grown. Following the success of their third studio album Free All Angels (2001), Ash debuted several new songs while touring throughout 2003. By October that year, they had travelled to Los Angeles, California, to record a follow-up album, which was co-produced by Nick Raskulinecz and the band. Recording sessions were held at Sound City Studios in Van Nuys and at Chalice Studios, Hollywood. Meltdown, which is described as a hard rock album, drew comparisons to the work of The Smashing Pumpkins and critics said the guitar work resembles that of Black Sabbath and Metallica.
