Before the band's set at the 2004 Download Festival, Ulrich was rushed to the hospital after having an anxiety seizure and was unable to perform. Hetfield searched for last-minute volunteers to replace Ulrich. Slayer drummer Dave Lombardo and Slipknot drummer Joey Jordison volunteered. Lombardo performed "Battery" and "The Four Horsemen", Ulrich's drum technician Flemming Larsen performed "Fade to Black", and Jordison performed the remainder of the set. Having toured for two years in support of "St. Anger" on the Summer Sanitarium Tour 2003 and the Madly in Anger with the World Tour, with multi-platinum rock band Godsmack in support, Metallica took a break from performing and spent most of 2005 with friends and family. The band opened for The Rolling Stones at SBC Park in San Francisco on November 13 and 15, 2005.
