Matt Gangi’s electro-psych evolution has been years in the making. In 2008, when SPIN saw the now L.A.-based artist at CMJ, expectations of strummy freak-folk gave way to dance beats and confident stagecraft, sparking comparisons to artists as disparate as Brian Jonestown Massacre and the Books. Now a duo with drummer and multi-instrumentalist Eric Chramosta, Gangi is set to release his second album as GANGI, gesture is, on October 2 via his own Office of Analogue and Digital label. Following a spooky black-and-white video for multi-layered advance track “Outside Ones,” the second preview of the new album comes in the form of “Railways no. 1-27.” With crunching guitar, looping vocals, live drums, found-sound samples, and even a smattering of honking saxophone, it’s an intricate, everything-and-the-kitchen-sink bit of atmospheric pop that amply displays the pair’s addiction to tweaking old analogue gear. “You’ve got to pay attention,” Gangi sings, and that’s always good advice.
