Not only does Main have roots with Big Bang's Seungri, it appears the rookie group has ties to B.A.P's maknae Zelo.
Main's leader Il Han is gathering particular interest as he was once the vocal trainer to a slew of idol stars, including Zelo and Jewelry's Semi.
The other members boast impressive resumes as well, as member Si Hoon has worked on numerous OST tracks, while Jin Sung participated in the Ryu Jae Ha Music Festival.
Main, whose name stands for 'Music, Aspire, Impressive, Narrative,' released its debut single Love Is on February 26.
