current live looping technology (available as dedicated hardware since around 1995) allows one to 'clone' themselves musically in front of a live audience.

Not all loopers use the technology the way I do, but how I use it is that I can
play a bass line, loop it in real time and then move over to a drum set..........loop it in sync with the first bass loop and move over to a guitar or keyboard line.

It allows me to be a multi-instrumentalist and, even more importantly, to make compositional music that I just couldn't make with a band. It's also forced me to study as many interesting instruments as I can. Because I am looping them and then putting them down to move to another instrument it means I don't have to work for ten years to learn a
trumpet, for instance.............I can learn enough about the instrument to be able to play parts that are in my head.

It is, of course, not the only valid way of composing music, but I have been the leader of bands all of my life and I"ve never been happier about the direct connection between my vision and actually manifesting that vision on stage.

It's really cool technology and can even be used to learn how to solo over chord changes........used in a modest way to help teach oneself.

If you play any instruments, you might want to give it a try.
The cheapest one on the market is about $250.............and they go up from there.

good luck and enjoy your local hole in the wall blues joint.

the Mayor of Santa Cruz just started learning how to play leads over a standard blues progression using a DL-4 (that cheap model I mentioned).

Let me know if you still want to know more.
