Our Celebrate Brooklyn! pick of the week

The unlikely pairing of Irish rocker Glen Hansard and Czech pianist Markéta Irglová has been charming listeners since the understated 2007 musical “Once” introduced the world to their heart-felt folk rock, even earning them an Oscar for “Falling Slowly.”

Luckily, it wasn’t just a one-time thing, as the two have been collaborating ever since as The Swell Season, releasing two albums and touring all over the world — including the Prospect Park band shell on July 30 (see them in an intimate show for NPR first below).

Equally as lucky, the two’s romantic entanglement — and its subsequent dissolution, Richard and Linda Thompson-style — hasn’t prevented them from making hauntingly beautiful music together. The mismatched pair — he with his rough voice and heart-on-his-sleeve demeanor, she with her more youthful, calculated one — write swooning songs about love and heartache capped with gorgeous harmonies. It’s a performance that will surely stick with you long after you leave the band shell.

The Swell Season at the Prospect Park band shell [Prospect Park West and Ninth Street in Park Slope, (718) 855-7882], July 30 at 7:30 pm. For info, visit www.bricartsmedia.org.
