I was just approached by a band who want's to record their own demo. They asked me for some advice on specific things, and I fugured we could all benefit from a discussion on the do's and don't's of making a top notch demo. First let's talk about the pre-production stage. Do you "produce" your demos before recording, or do you record first, and then attack issues like chord voicing, arrangement, etc. With my own band, we usually have at least a 2 track running, and we regularily listen to recordings of our improv jams, as well as our rehearsals. I learn a lot from this and I think it really contributes to our music. What do you do?
