Yes it is - funny thing was I was first exposed to that music when I joined a contemporary Episcopalian church locally...(me not having any idea at the time what was going on between traditional and "progressives") - I kept asking them "why arent we singing the OLD music"...
Interestingly enough, our choirmaster is about 24 or 25. He's gotten his MS in Music from Roosevelt University in Chicago and now teaches there. His father was just ordained a priest in the ECUSA.
