A little theatrical lighting is nice my friend- We are a 5 piece that plays every weekend and decided to invest in a little lighting.. We bought 2 of the Chauvette 4 par LEDs .. http://www.zzounds.com/item--CHV4BAR
Everythings pretty much included with those- you can program or set at random (as we do) has a sensitivity switch on back ( you can run an xlr cable between 2 and they run together in sync)-- We also have a color strip we put behind the drums- but for a three piece like you guys the 4 par at a side and color strip up front might be perfect!
The color bar also has an auto feature that is sound activated- Have fun my man!!
I love the lights-adds a lot in some darker bars and looks great live.. Now im on CL looking for cheap used pieces all the time- Just got moonflowers and a jellyfish for about 40$ EACH and 2 panel LEDs from a bar that closed locally.. AND a praise for the 4par lighting leds the Chauvette was knocked down one night at a gig from as tall as it gets (8-9ft) fell flat on its face and still works like a charm! Happy Hunting~
