A unique lighting effect that I use is the "Bob The Flame Light" by Chauvet - they cost something like $40 each from Musicians Friend and I use one on either side of my keyboard. They look great, like real flames. They've even caused a little anxiety with the audience in the past week though it's easy enough to reassure them by putting your hand in the "flame". I'm always being asked where people can buy them for their home. I just use a little front lighting and the Bobs do the rest - giving the stage a nice ambience. Now if I could only figure out why they are called "Bob"...
