I assure you young callum, everything has timing, especially blastbeats, it all depends on your view of would non-drummers actually care if it was not in time, would they really be able to tell!! just playing fast with no real skill or technique. But i believe that everything must be played in correct timing and precisely as you like in the music's own Genre, without good timing, that to me does not make a good drummer, if any drummer at all. My thoughts are, only play whats within your ability, practice furthur, but don't try and play crazy stuff you can't manage live, because you feel silly if it all goes tit's-up and look rather gash!! Embarrasment nobody needs! Before any negative comeback, this is not directed at anyone, just like the Jerry Springer thought at the end of the show!!, Wise words!!
