Field Music’s David Brewis hasn’t decided to go it alone: School of Language is just his laptop side project, which in a way is a testament to tech. This solo effort built of bytes rocks nicely, buttressed by smoking guitar anthems like “Poor Boy” and “Disappointment ’99.” Angular funk makes “This is No Fun” a spirited jam, while the four-part concept pop of “Rockist” is a sonic Tower of Babel built with the help of Garageband, semiotics, and soul music. Brewis doesn’t seem to have wasted a moment in the studio during this sojourn. If the other two members of Field Music churn out solo projects this energetic, Thrill Jockey will have a four-headed Hydra on its hands.
