My sister and I had a bit of a laugh late last night conjecturing what types of music the angels might have played when God created the universe. (I can't remember where it is but it seems like I remember the Bible saying that there was music during the event.)
Heavy metal or hard rock on day 1. The earth and other rocks were formed on this day. But what popped into our heads, but a rather different looking group of angels then your usual illustration. Including a drummer angel who used his halo* for an additional percussion instrument. "ding ding"
*halos might not actually exist, at least not playable ones at any rate.
