DJ Showcases

Duh.. why didn't i think about this before.

i know at wedding showcases they may have 1 or 2 DJ's perform and 1 or 2 bands go on.

I'm not sure when it is but i think it's coming up in the spring.

It's called the ORT showcase and takes place at the Marriot in Uniondale. It's geared towards Bar and Bat Mizvah's, not weddings, but you will be able to watch 5 different DJ companies perform.
typically....

Body rock
EJ the DJ
Heart to Heart
DJ's Unlimited (aka DJ U)
umm.... and a few others here and there.
