Contrary to their name, Akdong Musician ("akdong" which means "develish" or "rascal" in Korean) are doing quite the angelic deed by donating their musical talent.

According to YG Entertainment, the sibling duo performed at the Hope For Lou Gehrig's Disease Concert With Park Seung-il & Sean on October 21st at the Konkuk University New Millennium Memorial Hall. This event was held by the Seung-il Hope Foundation, co-represented by former
basketball player Park Seung-il and Jinusean's Sean.

This is the third time such a concert has been held, all in the name of spreading awareness on Lou Gehrig's disease and raising funds to build a convalescent hospital for patients suffering from the disease.
