Hi, this is my first post and just reading the posted articles it will be the first of many!
I agree with with previous comments. A good muso can perform with a sole instrument without FX, loops, sound bites and backing tracks. Many years ago my set up was; an acoustic guitar, a mic and my voice. I would use the acoustic as a percussion instrument by tapping the sound board and also tap my foot on the base of the mic stand. I would never endorse drum machines as that is one less muso working.
