Okay so I didn't feel good today and I stayed home. While I happened to be flipping through the channels and I wound up watching the Ashlee Simpson show. I guess she was picking out her back up band. So that got me thinking..... When a pop acts wants like a "Rock" backup band (guitars bass drums) how does the band learn the music? Do they give them sheet music or recordings or something else? I wouldn't think recordings would be a good idea since they might leak on the internet or something. I dunno I was just wondering how the whole process of Pop backup bands worked I guess. Please don't make this a bashing thread like "WATCHING the Ashlee Simpson show would make me sick hahaha" or "What the same backup band that played the wrong song hahaha"
