I frequently use a printed short bio that details my professional qualifications outside of school. Students seem to appreciate knowing that their instructor has actually participated in the music industry, instead of merely teaching about it. They can see a list of the groups I've performed with, album projects I've worked on, agency and management contacts, promotional work I've done, etc. Also, within our online instructor information, I provide a link to my efolio, which details my work and educational background, and gives some professional samples.
