Query: I've heard their voices...

...and I never get tired of listening to them. These five guys have amazing clarity and range. Lucky for J-Bird, they were smart enough to pick them up. I have two favorites, I'll Hear Your Voice and Don't Tell Me You Do, although all songs on this cd are well-worth the price. This CD is a must have for anyone that loves crystal clear, pure harmony.
