There are two bands with the name Customer: #1. CUSTOMER - first released on IRK MEDIA back in the early 90's. It's a two man force of lofi samplers , fueled by hate for the customer / media driven / fake society that exists today.
this group makes fantastic digital hardcore with a passion.
#2. Customer is the beginning of what is commonly called the end. the idea is a simple one, creating music for the sake of creating music. there are no deep underlying themes in this music. in fact there aren't even any members because everyone is a customer.
