30 Seconds to Mars are set to break a new record this year for performing the most shows during a single album cycle.

If all goes as planned, the band's 300th show at New York's Hammerstein Ballroom on Dec. 7 will mark the rockers' place in the Guinness World Records. The group, fronted by the mesh-loving Jared Leto, has been promoting their latest album, 'This Is War,' for nearly two years. The LP was released on Dec. 4, 2009.

“We have been on the road for an incredible and insane two years and thought what better way to celebrate the end of this phenomenal journey than with a week of special shows in New York City," Leto said in a press release. "We thought documenting this for posterity with the Guinness Book of World Records would be fun especially as we aren’t any good at growing our fingernails very long or cultivating the world’s largest squash.”

To celebrate their milestone, the band is planning several shows leading up to their Dec. 7 performance. Tickets will be available for purchase by the public on Oct. 22 at 10AM EST, and American Express card members can purchase tickets in advance beginning Monday, Oct. 17.

'This Is War' scored 30 Seconds to Mars two consecutive No. 1 singles with its title track and 'Kings & Queens,' as well as a Top 10 single with 'Closer to the Edge.' The third studio album from the three-piece has sold more than 1.5 million copies worldwide.
