Demo
A demo is a musical idea, recorded to help other musicians "visualize" where the songwriter wants to take a particular guitar riff. This riff was introduced to my band mates, but at the time I was not fully aware of the idea. I liked the riff, which was influenced by The Strokes' Someday (which I first heard in early 2002). "Last Nite" by The Strokes is good, too.
