Kurt Rosenwinkel is one of the greatest, most original contemporary guitarists and composers IMHO. To my ear he is a next generation Pat Metheny (also one of the greatest jazz guitarists and composers still very active).
If you’re ready to check out one of his albums I would recommend starting with “The Next Step”. It’s full of amazing playing and writing; modern, complex, yet still very approachable. It made such an impression on me when I first laid ears on it that I remember exactly where I was – getting ready to play a gig at The Cellar.
