The more you listen to Karma and modern WS arps, the more you realize that arrangers ARE dead. There is no future. They have been deliberately relegated to playing legacy music styles ONLY, and if you want to sound REMOTELY contemporary (within the last 15-20 years!), you are simply going to have to go out and buy a WS.
