ZEROBASEONE, the K-pop boy band formed through the reality talent competition "Boys Planet," debuted Monday with the extended play "Youth in the Shade."

The nine-member group's EP consists of six tracks and is fronted by the single "In Bloom," which has a music video that was released alongside the record.

"In Bloom" is a drum and bass track that pays homage to Norwegian band a-ha's synth-pop classic "Take On Me," according to a report by K-pop news website Soompi.
