f(x) Through the Years: Gallery
Formed in 2009 by S.M. Entertainment, f(x) has become one of K-pop's biggest international acts, even performing at SXSW in Austin, Texas in 2013.
Over the course of their eight year career in the music industry, the electro-pop girl group—currently comprised of singer-dancers Victoria, Amber, Luna and Krystal—released four full-length albums and two EPs.
While the band is currently, hopefully, working behind the scenes on new music for fans, click through the gallery above to reminisce with photos of the girls through the years.
