I was able to get this one on my own, along with the 4 of a kind, there's no I in band hero, and the 11x multiplier. I used one mic, 3 headsets in front of a fan on expert. I used the GHWT import of "no sleep til brooklyn" and got 1.3 million points. There's also 2 band moments to get the 11x multiplier. If you don't have that song, American Pie will get you 1.6 million and there's I believe 5 band moments.
