I have no hesitation in recommending this recording for lovers of the '70 experiments in rock/soul/jazz/fusion. The Crusaders formed their sound together when they were barely in their twenties, and by the time they recorded this wonderful stew of funk etudes, they were as one mind. Though the music may be "simple" (groove and uncomplicated melodies are the order of the day), that does not mean it lacks passion or excellence. This is some of happiest music I've ever heard; I loved it 30 years ago, I love it still.
