Theory IS unneccessary for ANY kind of music. All you need to do is play notes that sound good.
The advantage of theory is that it allows you to understand why the notes sound good - and therefore, to play more notes (or less notes, each with greater impact), each of which sound better, and which relate better to the music. Theory also allows you to easily step into genres other than those that you are used to, because music theory is universal.
You CAN play without theory. But it's foolish to limit yourself.
Honestly, just because I CAN walk from here to California does not mean I won't catch a plane when vacation time rolls around!
