I watched their performance on TV, I was stunned at how good they were. A suggestion for other reaction, would be Leonid and friends. They are a group from Russia. They absolutely rock. They do cover songs from classic 70s and 80s American bands. They have an original, I believe, song Called “speck of dust” it has many elements and I think you and your viewers would enjoy them. I’ve only seen 2 or 3 reactors profile them.
