One of the Dave Brubeck Quartet's lesser-known albums, this LP features the group performing six instrumental versions of songs from The Real Ambassadors plus "Dizzy Ditty" and a 12-minute rendition of "Brandenburg Gate." Brubeck, altoist Paul Desmond, bassist Eugene Wright and drummer Joe Morello seem inspired during this concert by the fresh material, making this hard-to-find album a bit of a collector's item.
