Rockers 30 Seconds to Mars are set to make history in December for performing the most shows during a single album cycle.
The group has been promoting its latest record "This Is War" since its release in December, 2009, and now the band's hard work has paid off.
The hitmakers will perform their 300th show at the Hammerstein Ballroom in New York City on December 7 and then kick-off a week of special shows to celebrate the milestone.
Frontman Jared Leto says, "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.
"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."
