Firstly, let me say that I've been playing guitar for a couple of years now. I know a few scales (Major, Minor, Blues, Harmonic Minor) and the basic chords with it's different shapes. I've also learned a few licks, which allows me to do some simple improvisation (mostly bluesy/rock licks). All in all, I have very basic knowledge on music theory.
I'm in a band and my rhythm playing basically consists on playing the chords on every beat, with some variations (strumming pattern changes, arpeggio, etc), which gets a little boring (at least to me).
I would like some advice on techniques for improving my rhythm guitar playing (and ways to develop such techniques). Maybe some way to play along with the melody while still playing chords, using fills between chords change (like David Gilmour in Time for example), chords substitutions, etc.
Just to help showing where I'm aiming at, I really like Eric Clapton's arrangements (I like most of his work, but I'm focusing here at the Cream/Layla era) and I love Hendrix' rhythm playing (Hey Joe for example). Basically, blues and blues rock rhythm playing.
Thanks a lot!
