I'm working with a country guitar player that ups the tempo of most all his cover tunes. To play typical 1-5 thumps at the speeds he plays doesnt sound well. Like bluegrass on steroids. What are suggested methods of covering very quick chord changes while maintaining a sensible rhythm? I've been playing root, 3rds and a triad to return to the root of the next chord. Its like time is compressed and I run out of it to cover all the chords in a given measure. Thanks.
