Actually, Penderecki's music has changed significantly since the 1960s.
His style has shifted from radical modernism to (what I would call) heavy
post-romanticism.

Penderecki's monumental vocal works are often the most interesting ones.
Do you know the Seven Gates of Jerusalem (Penderecki's Seventh Symphony,
written before the Sixth!)??? Like the Requiem, it's quite a powerful -
if not heavy - work...  But, sincerely, there is nothing to beat the
WONDERFUL St. Luke's Passion (1966).  This is still a modernist score,
but the composer integrates Gregorian themes in a most original framework.
From my perspective, this is one of the most moving 20th century musical
works.  I urge you to discover this stunning masterpiece:
