What do you guys think of his playing. I was not really a tool fan until I bought their new album because I was curious why there were magnifying glasses on the packaging. I heard some pretty tasty bass lines on the album and i liked the music too. What do you think of Justin Chancellor's playing and I know that there was another bassist before Justin. What was he like? Who is better? Someone told me that Tool's earlier music is heavier and things changed when the first bassist left. Is that true?
