We're officially a week into summer, but we're not taking any time off. We have put away the winter music -- Schumann and Brahms chamber and piano music -- for lashings of bluegrass -- mostly Chris Thile and his wonderful band, Punch Brothers -- and our favorite album of the year thus far, "An Awesome Wave" by ∆, also known by their keystroke, Alt-j. Brilliant, intelligent, poetic, typographic, 21st-century pop. (Drawing letters and wrangling code is a time-intensive activity; it helps to have a little light relief.)
