Query: A major disappointment

What went wrong here? The musicians are excellent: Russell Malone, Billy Hart, and Barron himself. But it's all so derivative and dull. At times, the group wants to sound like Horace Silver. And then it's Ellington. And then it's Miles. Ultimately, nothing comes off. As for jazz violin, well, it's almost bearable. A bummer.
