They aren't the same: System F is Ferry Corsten and Gouryella is Ferry Corsten together with Dj Tiësto.
Other songs by Gouryella: Tenshi and Walhalla

Originally posted by mindshooter My favourit track is: System F - out of the blue (Mars and mystre mix) now i have realized that its the same track as Gouryella - Gouryella wich one came first? By the way isn´t the same producers behind the 2 groups?

there aren't the same track at all..
I dunno about the mArs & Mystre mix.. never heard it..
but Out of The Blue came out in 98
whereas Gouryella in 99..

Yeah i know that the original "Out of the blue" doesnt sound like gouryella but the Mars and mystre mix does!
download it and have a look.....only difference i found when i heard it on a internet-radio was that in the gouryella track they had cut away one of the best pieces....
