The title Go is a perfect fit for the Sigur Ros frontman's debut album. It's a tiny word loaded with affirmation and dynamism, much like Jonsi's inimitable falsetto, a delicate instrument with immense power behind it. Like his work with Sigur Ros, huge symphonic crescendos are almost required to keep up with him; they serve to melt the frosted touch of his coos, in return giving listeners uncontrollable chills. Composer Nico Muhly lightens the mood with jovial beats and chirping flutes, and Jonsi even gives up some of his mystique by singing in (mostly) English. Beautiful.
