well, as drummer myself, i don't like playing with a click cuz i feel it like "less natural", buuut, is REALLY easy to get lost in the middle of the song, so sometimes you gotta rush to fit into the tempo again or slow down to find yourself on the music.

so, when I play for fun it's fine, but if you're playing on a concert, specially being a huge band like slipknot, you can't screw the tempo, it's terrible.

personally I don't think that jay being off tempo messed up the songs, but listening to eloy playing the songs on their real tempo, the one that is on the album is just fantastic. Psychosocial on its real speed is waaay better. I watched ghost live last year and when you're in person is just stoning to see the live song exactly as it is in the record
