About f(x)
f(x) debuted under SM Entertainment on September 5, 2009. The group — now consisting of Luna, Amber, and Krystal (with Victoria as inactive and Sulli who passed away in 2019) — became known for their experimental, concept-heavy music that often challenged what a K-pop girl group could be. Albums like "Pink Tape" and "Red Light" are considered among the most artistically forward K-pop releases of the decade. The group has not officially disbanded but has been on indefinite hiatus since 2019.
