Drumroll, please... 30 Seconds to Mars will make musical history next month, when they'll play their 300th show in support of their most recent album 'This Is War.' So how is that history? Turns out the band will have performed the most shows in support of an album during its active cycle. Congrats to the band for achieving this impress feat. 'This Is War' hit stores on Dec. 4th, 2009.

The Jared Leto-fronted atmospheric rockers will head to the Hammerstein Ballroom in New York City on Dec. 7th for the milestone performance. 30 Seconds to Mars will continue the celebration and embark on a week of shows to further commemorate the historic event.

"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 statement.

He continued, "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."
