Back when Ducktails dropped III: Arcade Dynamics, the goopy pop project was solely the domain of Real Estate guitarist Matt Mondanile. But for the chillwave graduate’s just-out fourth album, The Flower Lane, he’s press-ganged himself a band of rogue players also on loan from other acts. Both (Joel) Ford & (Daniel) Lopatin drop by. New Jersey band Big Troubles assists. Jessa Farkas of Future Shuttle and Sam Mehran of Outer Limitz sing. The expansion in personnel has likewise led to growth in the Ducktails sound, which now employs the sort of soft rock explored by Destroyer of late, plus a little bit of the smooth groove that our man Toro Y Moi has become so adept at creating. “Letter of Intent” is the album’s first single — all drifty and synthy with unexpected cameos from wind instruments — and the just-out video for it matches the mood quite well. Through a muted color scheme, we see awesome bubbles, excellent architecture, despondent drumming, inaccurate instruments, and loads of warm winter wear. The entire thing was shot in Central Park, according to Rolling Stone, on one of the coldest days of the year.
