I agree with bigtimemusic lover: the sound quality of "The Ultimate Otis Redding" is sub-par. Although the choice of tracks is admirable, the mushy audio does not do Otis justice. If you still have your turntable hooked up, compare a hit track from an Otis LP (such as Atco's "The Best of Otis Redding") to the same track on this CD. You will be amazed at the difference.
If I were to own just one Otis Redding recording, it would have to be "Live in Europe". The energy, the crowd and - most especially - Otis' electric performance - make "Live in Europe" indispensable.
