Searching forum threads, I was surprised how little discussion of Andy Summers there has been. I’ve been listening to and enjoying his recent release, Metal Dog. It’s instrumental...a bit experimental (he calls it, "avant garde") but definitely accessible. Very good sonics. An interesting interview about that recording at the link here,
http://www.goldminemag.com/article/andy-summers-unleashes-metal-dog Andy Summers’ post-Police, (largely solo) work including collaborations with Robert Fripp and a few others is well worth exploring. The compositions, as in Metal Dog, bear repeated listening, he generally takes a fresh, original approach (consider the Mingus and Monk tributes), the musicianship and sound quality are, almost without exception, excellent. Album to album there is great variety as he explores a number of different musical genre and styles.
Personal favorites: The Golden Wire, First You Build a Cloud, Mysterious Barricades, Last Dance of Mr. X, Green Chimneys and now, Metal Dog.
Spotify has much of his catalog if you are interested in exploring. Hope you will be.
