One of my favorite voices - I liked everything he did, though Asia was a bit too "pop" for me. Those King Crimson albums he was on are my favorites by KC.
R.I.P. John Wetton (King Crimson/Asia)
John Wetton passed away a few days ago, age 67. While I never listened to Asia, I was a fan of the mid-70's small version of King Crimson (Lark's Tongue in Aspic, Red, Starless and Bible Black and the live USA LP). He was a fine writer, vocalist and bassist. As usual, there's a pretty complete article in the New York Times obit section if you're interested.
