In Music What Is a Loop, and What Is Its Purpose?
I recently attended a concert for a very famous rock band known for their great live performances. Before one song, the front man had a brief conversation with a sound guy. He said to the crowd, that the loop was not working, but then he said "forget the loop, we'll do it 'off the record'". When they performed the song, it sounded perfectly normal. No elements seemed to be missing. It didn't sound any different than the rest of the concert, and I am quite certain they did NOT lip sync it.
Can anyone tell me what this was probably about?
