Beyond what/how to record....
My band created a medley demo that was about 4 minutes that contained bits of songs that really highlighted our strong points. We are an all around cover band so we included classic rock, country, alternative rock, funk, and r&b on the demo. Rather than give a venue manager a CD with 15 minutes of music, they could tell what kind of band we were after 3 minutes.
