4men definitely have a lot in store for their�upcoming concert series, '2013 4men Concert: I'll Let You Listen', including a collaboration with their mentor Vibe's Yoon Min Soo and the first live performance of their new single "Propose Song".

4men will also be performing their first stage of "You're My Light" from their new album 'Thank You' as well as doing something fans don't get to see often by holding their own solo stages.

Their agency stated, "4men, who are awaiting their nationwide tour concert, are putting all of their time and effort into practicing while dripping sweat everyday in the practice room. 4men will show a new image through the concert, which will feature impressive live performances and even dance stages. We ask for your love and support."

The group will be kicking off their concert series at the�Yonsei 100th Memorial Hall in Seoul on May 17-19th.
