I thought it was a good mix. I did liked the fast mixing. And I also think it is good enough to send it to club. If they don’t like it at least you gave it a try. If you send the mix on a cd them maybe you can send it as wav. If you mail them the mix then you can send it as mp3. The advantage of a mp 3 is that you can listen to it on multiple platforms like laptop or phone.
The mix itself was good but I think there is room for improvement. The transitions were a little sloppy and loud sometimes. try to use your EQ’s for smoother transitions. I hope you get the gig. Let me know if you did.
Good luck with it.
