"[2] Keszler has also toured or collaborated with artists such as Tony Conrad, Jandek, Loren Connors, the Iceland Symphony Orchestra and Oneohtrix Point Never, and has released several solo albums since 2008.

[5] Working as a drummer, guitarist, and composer in New York, Keszler soon became known for accompanying his music performances with live installations and visual elements, sometimes utilizing drawings, diagrams, screen prints, and writings.

His sound installations and visual pieces "often use microprocessor-controlled motors to strike, scrape and vibrate various lengths of piano wire as well as other materials.

Wire described one track as "a recording of a quintet performing with Keszler's 14 string, 40 x 15 foot mechanical sound installation, Cold Pin.

The installation consists of 'three to five 25 foot long strings with motors, wire, a curved wall, micro-controllers, pick-ups and phono cables'."

Music critic Fred Thomas of AllMusic gave Alps 4/5 stars, writing that "these duets merge Ambarchi's symphonic and sometimes storytelling feedback with nonstop blasts of scattershot drumming from Keszler for an attack of noisy improvisation.

Keszler's fluid and anxiety-ridden percussion style is a perfect companion for Ambarchi's grizzly guitar stabs and horror movie drones.

The New York Times described Keszler's work as "using rigorously conceived scores to harness the inchoate energy of improvisation and its capacity for surprise.
