Query: Compressed Fidelity

Of all the CDs I've purchased this one is the lowest quality of fidelity ever. The producers have compressed the life out of a high energy artist. This one can only sound good on earbuds or tiny computer speakers. CDs are usually known for full fidelity, sharp crisp highs, lots of dynamics, close to a live performance sound. The producers have turned a high quality performer's work into mush. Thanks Sony and Angelo Medina, you've produced a new low.
