I was just looking at a list of new music releases for September and it seems that hardly anyone releases recordings these days with out a parade of guest musicians "dropping by." Seems you can't buy a cd without Sheryl Crow or Willie Nelson making a appearance on it. I assume this is the music industry's idea and I doubt the artist has much say about it, but I wondered if anyone can pin point when this started? Slash on a Bob Dylan cd? Sting on a James Taylor? I remember (and still play)those wonderful Wolf and Waters with English rock stars albums, but this is something different.

Thanks for indulging me.
