As a casual observer - but one who LOVES music - I thoroughly enjoyed this clip and was fully invested in it. I also hope they finish the song. Some folks might not appreciate the repetition, but it's all part of the process...they've got to formulate something, and ingrain it in their heads. Watching crafters masterfully craft their art...impressive, inspiring and fascinating; what an honour! Vlad - you could tell - was just blown away by the experience :-)
