Just my opinion, but there is nothing more amateur-hour than a band playing a live-gig (whether originals or covers) that has long stops between almost every song where- they mess with there tuning, effects, switching instruments, etc... as I said to each there own, but please don't kid yourselves, thinking any of your favortie Djent bands are heavier than Zep or Sabbath... because they tuned their bass down to F# Low...sorry if that hurts but it is the truth.
