30 Seconds To Mars are on course to set a new Guinness World Record for the most live shows played during one album cycle.
The band, fronted by Jared Leto, will play their 300th show in December for recent album 'This Is War'.
In a statement Leto said: ''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?'
He added: "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."
30 Seconds To Mars have been on tour since 2009 playing more than 60 different cities across six different continents.
