Interesting to see on these lists some mellow jazz next to some rockers. For those interested in jazz, I've found a current artist, Nils Landgren, whom does a wide range of stuff from funk to traditional jazz forms. He also works often with a pianist, Wolfgang Haffner.
Landgren is a Swedish trombonist, so it shouldn't shock that he chose to cover Abba (Album- Funky Abba). The miracle is that he has made the unlistenable not just palatable, but darned good. Likely you'd not recognize any of it without help.
