i think u misread my messege or i wrongly wrote it..but what i
meant was that metal is NOT improvisation but all planned which
makes it so technical as they come up with such complicated rythm
and structures and they manage play it with superb precision...and
i doubt u will be able to find a song which is all double
pedalling.
i admit some really technical metal arent that nice in terms of
tune but im always in awe at their compatibility and skills which
require years, maybe decades of practice to be where they are
now!!

anyway we're veering off topic!! can someone provide more details
for metal drumming lessons!!!
