Should've researched it more... . After much much excitement and almost 20 bucks layed out I was extremely disappointed. The music was really slow, boring and rather dull. The songs start to seem like they're the same as the lack ones. Maybe I'm just too used to other trance but I couldnt' find any trance in this cd

Ex Output:
NEG

A must for any cross country or track runner . I heard this CD when I was watching an indoor track meet. One of my dad's runners showed me the CD and I listened to it. My Mom bought it for me back in 1997 as one of the first CDs I ever had. It is probably the best classical music CD I have ever owned or to which I have listened. If you run cross country or track this CD is a must as it gets you going gradually, especially the song "Titles." A must CD for runners and anyone else who likes nice classical background music.

Ex Output:
POS

Mediocre Music with Horrible Vibrato . The first time I heard about Antony and the Johnsons was from a friend of mine that told me about Rufus Wainwright and was listening to a new artist that was quite incredible.  I decided to do some investigating about this Antony at a local Barnes & Noble and what I discovered was very, very dissapointing.    I find the music to be well written instrumentally and layered quite well, but Antony's voice is very over the top and fake.  By fake, I mean his use of vibrato, which is very rapid and used in a way that comes out as forced and sheeplike (not natural).  Professional voice instructors teach that the correct way to use vibrato is at the right speed: five to six vibrations per second.  It is evident that Antony's "trained" sounding voice is not trained at all in this realm.    Another thing about this band and record that I find very horrible is the lyrics to the songs.  The artist seems confused or regretful of his own gender using a sorrowful and painful delivery of these wailings.  The lyrics hold no attraction or relation to the listening, which lends the listener to a pitiful and almost annoying view of the music itself because of this.    My conclusion is that this is a terrible record and the singer needs to pursue professional voice lessons... and help
