Something very similar happened to me about two month ago. The club I am resident in booked DJ Luck and MC Neat (2 massive UK garage artists). They wanted me to DJ either side of their set. All good ye… apart from I am not a Garage DJ…..I am a dance/club/house DJ.
Anyway, I decide to take the gig, I done a bit of research in to garage music, also asked DDJT members for help…….. Next thing I know I am performing a full on garage set alongside LUCK & NEAT!….. And I absolutely loved every second of it, probably one of the best nights I have ever done.
So ye, don’t turn down the opportunity, I would defiantly take the gig, just brush up on your music, do a bit of planning and go for it!!
Good Luck …lets me know how it goes, if you do decide to take the gig 😉
