After Changsub and Ilhoon, Peniel is next to release a solo track for the “Piece of BTOB” project!
Peniel’s track was produced in collaboration with his brother-in-law and producer KAIROS, who has worked on songs such as Suzy‘s “Pretend” and TWICE’s “Next Page.” The song is scheduled to be released in late June.
Meanwhile, “Piece of BTOB” features one member releasing a solo track each month. It kicked off with Changsub’s “At The End” in April and continued with Ilhoon’s “Fancy Shoes” in May.
