2AM's Seulong will return with his first solo single album titled Normal. This will be the singer's first release under Sidus HQ and since his departure from JYP Entertainment earlier this year.

One of the tracks,"Tell Me," is a simple R&B track with poetic lyrics while the other track, "Mood Swing," features a vintage sound and a rap verse.

The Korean idol worked on the tracks himself with composing and writing credits for both "Tell Me" and "Mood Swing."

"Mood Swing" and the accompanying music video, which Seulong is said to have helped direct and develop the style concept for, is planned for release on May 19, with the Normal single album scheduled to officially drop at noon KST on May 22.
