System F is an alias of Ferry Corsten. The first single under the System F alias was "Out Of The Blue". This track was released in March 1999 on Tsunami, a label of Dutch record company Purple Eye. Ferry had already finished this track in 1998. Because he released some other tracks on Tsunami, he already had contact with Maykel Piron. After listening to the track, Maykel immediately signed the track. Before the official release, some limited one-sided promo vinyls were send to a few DJs.
