FB is a one-time artist alias created by Dutch DJ and producer Ferry Corsten and Italian DJ and producer Benny Benassi. Due to the single music project that FB worked on, technically FB features one more member, Russian/Nigerian gospel and electronic vocal singer Edun. There are two tracks under this alias, Who's Knockin'? (Ferry Corsten Remix), and Who's Knockin? (Benny Benassi Remix).
