We posted the smooth, end of the night vibes of “Why,” Alpine’s collaboration with Maya Jane Coles, back at the tail end of last year, and since then the London based duo have not been slacking. “Why” was in fact the first of three collaborations with exciting producers, and below I invite you to listen to the other two. Alpines themselves are on the come-up, having last year released the wonderful Drive EP, which showed off the strident, powerful vocals of lead singer Catherine Pockson, who comes across as a more emotional La Roux, as well as the sparse but perfectly executed post- The xx and James Blake production techniques of Bob Matthews.

Anyway, back to the present, and to the two collaborations, both of which may now be a couple of weeks old, but are truly unmissable. First up is “Gold”, produced with Craze & Hoax, which is full of hip-hop leaning percussion and soaring, heartbroken vocals that should be sung standing on a windswept cliff looking out over dark stormy waters. Now “Gold” is great, but “Tremors”, produced by innovative bass music trio Dark Sky, is on some next, next hype. Starting off slow, the beat slowly builds and eventually engulfs you in synth washes and the occasional seismic base wobble, finally bursting into a raveyness for the final minute.

You guys feeling Alpines as much as I am?
