Could anyone suggest groups/videos on YouTube performing warm up exercises? There's so much great content from the major universities/performing ensembles that feature their concert performances, but I'm really interested in showing my students these professionals' warm up processes as a full band.
I watched Eugene Corporon direct a rehearsal for 90 minutes where they only played a Bb scale/longtones/exercises years ago. Blew my mind. Some good DCI videos exist, but what about in the concert setting?
