I was lucky enough to discover the rich, earthy music of Eric Burdon and War about six months ago; when I bought the album Eric Burdon Declares War. (I love the album title, too!)
War had an expansive and funky sound... it is very joyful music.
('Spirit' is the song title.)
With the components of War's sound including a horn section; some Latin percussion; Burdon's strong, compelling vocals; Lee Oskar's harmonica...
and funk... lots of that!
