After starting working on a new album in May 2021, BamBam announced it on December 13. The release was preceded by the single "Who Are You" on December 28, which saw him collaborate with
Kang Seul-gi of
Red Velvet and for which he was credited as a composer, lyricist, producer and mixing engineer.
B was published on January 18, 2022 along with the music video of "Slow Mo". The title of the record is a reference to the singer's name, and, as there are two versions of the album (pink and yellow), the letter gets doubled to form his initials, "BB". == Music and lyrics ==
