After the conclusion of the Rock the Nation Tour, Kiss performed only sporadically for a number of years. The group played two shows in 2005, and another six in 2006. Four of the 2006 shows were July concerts in Japan, including two dates (July 22 and 23) as a headlining act at the 2006 Udo Music Festival. Kiss performed four July 2007 concerts, three of which were dubbed the Hit 'N Run Tour. Prior to the final show on July 27, Stanley was hospitalized with an extremely rapid heartbeat. In his absence, Kiss performed in concert as a trio for the first time since 1982. This was the first Kiss concert that Stanley had missed during his then 34-year tenure with the group.
