Example Input: This CD is amazing. Lhasa and her band demonstrate top musicianship combined with abundant passion. If you are a music fan with a large collection and taste of music, you must add this CD to your collection. It will be among your top 10 favorites. And that goes for music fans with modest CD collections too! And if you get a chance to see them perform live they are even better. I saw her last year in Montreal. Wow!

Positive
