Slash quotes that,
"he's excited at the opportunity the contest will provide for emerging acts to gain recognition. The contest coincides with the "Shred with Slash" guitar strings promotion that offers a 2-hour master class with the guitarist, among other prizes."
*This is a great promotion and marketing strategy because it gets consumers that are also involved with music excited for not only for Slash's solo album to come out, but gives musicians an opportunity to put their music out to the public and be involved in a once in a lifetime opportunity. The fact that Slash will be personally listening to everyone's submission can make them a bigger fan of Slash and his music.
