I don't think people should be anti slash for doing this.

However..

I'm not a fan of the genre as I see AI and similar shows as nothing more than karokee contests. It seems to me that what they do is find the people who are the best at doing COVERS, and then ask them to be creative and give them record contracts. Why would that work? That a person is good at singing others songs doesn't mean they will write good things, and likewise in a sence finding someone who can sing good in a variety of styles just turns into "jack of all trades master of none". What of people like Brian Johnson of Ac/Dc who sound awesome in one style - his hardrock screach...he'd be kicked out when he sang a robbie williams ballad badly. It's a stupid idea IMO. So i dont like the concept.

But that said, this is where the industry is at, it's what the market is doing. Slash is a professional musican at an eliete level, and it makes sence for him to get involved in the current trends of the market. It's his job.
