Their faces have literally stopped traffic.
Asphalt Orchestra is a giddy band camp fantasy brought to life: What if the section leaders formed a marching band that was actually cool? They’d play only the music they listened to in the parking lot between rehearsals. Stuff like Frank Zappa, Bjork, and Swedish metal band Meshuggah would be in; showtunes and “The Horse” would disappear completely. Well, thanks to a Rockefeller Foundation grant and the Bang On a Can new music organization, the dream is realized. And the result is… a little geeky.
That is what I said in this review at PopMatters. Read more there! Here's one more paragraph:
Don’t get me wrong, the Asphalt Orchestra can blow. Listening to the insane repeated notes of their take on Meshuggah’s “Electric Red”, my band director wife was impressed: “They really know how to use their tongues”. They also know how to count. Zappa and Meshuggah belong to an elite musical club: they’re widely known for writing songs with shifting meters, or with different instruments playing in different meters at the same time. “Electric Red” has passages in 23/16 or something. If you’re tempted to figure it out, you’re probably one of those maniacs who likes to complete Sudokus in your head.
