Yeah, Mako really stands out in the Rainbow 7 concert. I'm only halfway through watching it, but I really liked the first part of the concert. Was both surprised and happy to see (and hear!) Mako so often. She really shines, and once she has control of her voice she sounds really, really great.
Mushoku Toumei na Mama de is one of my favourite tracks from the album and the performance just sent chills down my spine. Beautiful!
