Maybe Donald Byrd said all he had to say in the jazz idiom. The Harpers were just OK, and that's because anything less than outstanding, sounds just OK. After listening to jazz all my life, I'm only impressed by something that's outstanding.
Although Donald Byrd produced many outstanding pieces of work over the years in jazz, he felt it was time to change grooves, and while I didn't agree with him at the time, now I understand his motivation and point of view a lot better. As a listener, I feel the need to change grooves from time to time, maybe that's why I can tread lightly into Donald's new groove.
Horace Silver is someone who withstood the test of time and never changed grooves completely; his music stayed somewhere in the broad jazz arena, while borrowing from other cultures from time to time; this is what kept his music fresh. With the approval of the rest of the aficionados, I would like to move on to Horace Silver after we have finished with Donald Byrd.
Enjoy the music.
