So I'm a pretty good lead guitarist but I feel my rhythm guitar is pretty mediocre. I can play all the common open and bar chords like major, minor, 7ths, and suspended 4ths. I want to get in to using more interesting chord voicings in my playing does anyone know of some good lessons on rhythm guitar or songs to learn?
The most difficult rythme I've bumped into in awhile is a Song called Trains by Porcupine Tree. It sounds simple until you get into it. Of course.. .what is difficult for one person is easy for another... and visa versa.

Youtube is a good resource. If you seach "Chord Voicings" you get all kinds of lessons.
