Pink Tape - f(x)

Released in July 2013 by SM Entertainment, this second studio album remains a high-water mark of avant-garde Korean pop. Packaged ingeniously as a pink VHS cassette, Pink Tape moved far beyond title track Rum Pum Pum Pum into daring art-pop and electro-funk. Standout tracks like Shadow explore eerie melodic minimalism, Airplane surges with soaring electronic dance music euphoria, and Step delivers infectious horn-driven bounce. It established f(x) as pop visionaries who treated the album as an experimental concept piece.
