My band and I are thinking of spicing up the stage show since the music is relatively chilled out and flowing. So, we need some psychedelic lights to compliment the music. Mainly we want to have some lights we can set on the front of the stage, that will shine back on us. We want to have one light on the bass drum head, and at least 1 on the guitar amps, and 1 on the bass amp. We want the lights to put out some swirling psychedelic patterns.The lights preferably need to be cheap, reliable and able to run on their own, without us having to mess with them during the set. Any ideas?
