The Mumford moment overtook TD Garden on Tuesday.
Mumford & Sons launched its North American tour with a sold-out Garden show, which leads to a few more sold-out arenas and then to the Grammy Awards, where the English band’s “Babel” is nominated for Album of the Year and has songs contesting in Americana song and rock song of the year.

This is a very interesting review, for what's between the lines. Nuanced in such a way that non-fans are going to feel relieved that they weren't there, yet not saying anything that would directly alienate fans.
Show was awesome! One of the best I've seen in a really long time. Ben Howard was really good, too.
