[3] It is a concept album about "a couple of maintenance veterans named Dave and Mike who work in Cavanaugh, a fictional mixed-income housing unit in the also-fictional town of Detroit, Florida.

"[4] Nate Patrin of Pitchfork gave the album a 7.2 out of 10, writing, "for his first full-length production job, Mike sets a tone as raw-nerved and abrasively contemplative as the concept demands.

"[6] Brett Uddenberg of San Diego Reader wrote, "this is a dense and diverse record that plays to the songwriting strengths of Mike and Serengeti and hints at greater things to come as their partnership evolves.
