Every year I attend the Fretboard Festival in Kalamazoo Michigan. This event bring together Musicians from all over as well as many vendors. In the past, bands of have sent me flyers, stickers, CD's etc. to hand out and promote. I am typically the only one there promoting Hard Rock and Metal, so there is not much competition.
I am looking to see if there are any bands interested in sending me stuff to promote. If there is, I will do the Festival. Let me know if you are interested. Here is a link to the festival. It usually brings about 3,000 people.
