Soulful jazz fusion ballads
I'm mainly a prog rock/metal guy, but I recently discovered Mike Stern and got completely addicted to his ballads. I can't stop listening to them! Songs like "Common Ground," "Goodbye Again," "After You," and "All Heart." Also, not exactly a ballad, but "Little Shoes" has one of the best guitar solos I've ever heard.
Another song with this kind of vibe that I absolutely love is "Vento" by Toninho Horta.
Someday, I'd love to learn these songs on guitar in a chord-melody style. I've seen some covers, and they sound amazing.
Can anyone recommend other songs and guitarists with this beautiful, soulful vibe?
