I've been letting this artist slip for several rounds now, always finding an excuse to take another artist instead. I tried to do so again this time, but I'm going to overcome the urge and just go with my gut:
Sting.
Ever since the Police went earlier in the draft, Sting has been on my board. In all honesty, I think his work since he left the Police has actually been better, though I don't expect that most would agree. He has obviously been less of a rock-and-roller since then, but really, it suits him. He's done jazz, he's done country, he's mixed in Arabian singing, he's experimented with instrumentation (like the use of the Northumbrian Pipe on The Soul Cages), and he's thrown the whole idea a change up and put out an album of Dowland's lute music, a Christmas album, and an album of symphonic remixes of his own songs. He doesn't allow himself to get pinned down and it really makes for a diverse and fantastic catalog.

Song I keep coming back to:
(Really odd video, there, Sting!)
