the purcell was sung by two countertenors...and the 'minimalist' piece was John Adam's Short Ride in a Fast Machine - great piece, but not really all that minimalist!
...from a John Adams interview in 1999:
Robert Davidson: It's clear that you've moved a long way from minimalism, though you are often described even now as a minimalist composer. What connection do you have with that music?
John Adams: My music has minimalist influences rather than being minimalist itself. When I first heard early minimalist music, I was greatly attracted to certain principles I heard in it - principles like clear tonal centres, clear pulse and slow harmonic rate of change. If you look at almost any one of my pieces, you see traces of those principles.
