B2K was an American boy band that gained popularity in the early 2000s. The group was formed in 1998 and consisted of members Omarion, J-Boog, Lil' Fizz, and Raz-B. They were known for their catchy R&B tunes and dynamic dance performances, with hits like "Bump, Bump, Bump" and "Uh Huh" achieving commercial success. B2K released their self-titled debut album in 2002, followed by "Pandemonium!" the same year. The group disbanded in 2004, but their influence on the pop and R&B scene remains significant, and they briefly reunited for "The Millennium Tour" in 2019.
