Although I listen to just about anything musically inclined, as far as the acoustic music is concerned, there are 2 people I recommend. Preston Reed is absolutely amazing. He turns an acoustic guitar into a whole band. He thumps out a beat while he plays a rhythym and lead at the same time and its all grooves! Another guy the Reed has worked with is Laurence Juber. Both are incredible but hard to find. try AcousticMusicResource.com
