When played in the grand tradition, the jazz trumpet exudes a clarion optimism that other instrumentalists find difficult to match. That the entire rhythm section as commandeered by Oscar Peterson can equal the ebullience of this brass troika gives this blowing session supreme a rare balance. Are the horns on? Consult the whirlwind "Daahoud." Can Peterson's foursome spar and counterpunch in kind? Check their imaginative support on the funky "Chicken Wings."
