Piazzolla is rolling in his grave.
Bruce Edwards screwed up and botched the arrangement for Histoire du Tango. The clarinet playing was great, but clearly none of the players had ever heard Piazzolla's signature piece, or they wouldn't have overlooked these really obvious blunders in Edwards' arrangement. I hesitate to call them mistakes--they feel more like Edwards was trying to leave his marks in the piece and utterly failed. The rest of the album is top shelf. Just do yourself a favor and delete tracks 1-4.
