First Narrows is the third Loscil album and the first in which Scott Morgan uses real instruments and input from other musicians. Using sound sources that ranged from sampled instruments to miscellaneous lo-fi mini-cassette recordings, Morgan generated music on computer by custom programming sequencing and processing designed so that no two performances of the patches would be exactly the same. In turn, Jason Zumpano on fender rhodes piano, Tim Loewen on guitar and Nyla Rany on cello improvised over those electronic sequences. Morgan then edited and mixed the live and premixed sections together.
First Narrows is named after the first gap to the entrance of the Burrard Inlet, over which the Lions Gate Bridge spans; the main entrance into Vancouver from the Pacific Ocean. By including a loscil track on their compilation of Canadian electronica alongside artists like Tim Hecker, Polmo Polpo, Ghislain Poirier and Thomas Jirku, the intr_version label confirmed that Loscil deserves placement among the unique practitioners of electronic sound arrangement.
