Surprised that the premier acapella group of our time hasn't been mentioned yet, TAKE 6!! Their debut album, 'Take 6', and the 2nd, '2 much 2 say'(?) are truly outstanding. They come from the Church but lean strongly into doo wop/jazz stylings. 1st time I saw them was on a Grammy show 15-20 years ago, the camera pans to the front row of the audience and sitting together, heads bobbin' with ear-to-ear grins, was Diana Ross, Quincy Jones, Stevie Wonder, and Michael Jackson!
