It’s great to add a classic Party DJ, along with something cool and fresh as well.
I would also suggest going for a party-style DJ, just before the band for 30 minutes, followed by the band for ninety minutes.
Add in something like Sax and DJ, Drummer with DJ, Daft Punk Tribute and close off with 30 minutes of big Christmas favorites.
Here are some more unique ideas, to really help your event stand out from the crowd this Christmas.
