Query: this is great

this album is great. starts with house in the first cd, it goes deeper and deeper and makes you just want to get up and dance. the second cd is even better, starts with really dark jungle and goes on to trance. trance is good music but lots of djs don't know how to handle it, they don't know how to use trance to make people dance but john digweed does a perfect job in this album.
