Here is a wonderful video from Isaac Wardell of Bifrost Arts, a collective of artists “bringing back” the hymn sing, speaking on collective singing/making music as a form of worship and how this has been neglected in the church over the last few years.  This is a really well-done piece.  In the background is “Joy, Joy” from their Advent album, Salvation Is Created: A Christmas Record From Bifrost Arts (get this!).
