Stylistically, the "Headquarters" album shows it to be influenced by the music of Steely Dan, with arranged horns and background vocals throughout.  Breithaupt says the tunes are "pop songs with too many chords!"  Also, some guitar work comes from guest artists Drew Zingg (who is best known for his work with Boz Scaggs and Steely Dan), as well as from Kim Mitchell and Rik Emmett (founder of the band Triumph).  Also making contributions on this album are Steely Dan trumpet player and musical director Michael Leonhart, with Julie Crochetière and David Blamires adding backup vocals.

Left (Monkey House album): Left is the title of a studio album by the music group Monkey House, released on June 3, 2016, on the Alma Records label, which is affiliated with the Universal Music Group.  It was mainly recorded at the Drive Shed in Toronto.  It was co-produced by Don Breithaupt and Peter Cardinali, and the engineer was John 'Beetle' Bailey.  After the increased popularity of their previous album from 2012, entitled "Headquarters", the leader of the band Don Breithaupt stated that "Part of the buzz for me on this album is that I sense a lot of people [were] waiting for it.  I keep getting inquiries from people from all over the world giving me grief for taking so long, but that’s a fun situation to be in."  Once again, this release has raised comparisons to the music group Steely Dan.  "There's only one comparison really, and that's Steely Dan, and in particular, the Aja-Gaucho period", states jazzcorner.com.  The album title "Left" is derived from the fact that Breithaupt made a big move from Toronto, to the "left coast", or west coast of the United States, setting up a new home in the Los Angeles, California area prior to the production and recording of the album.  He states that some of the tunes originated on his long drive across the wide open spaces in North America.  The album features contributions from Steely Dan veterans Michael Leonhart, Elliott Randall, Jay Graydon and Drew Zingg, and includes background vocals from Lucy Woodward (Snarky Puppy), as well as David Blamires (Pat Metheny Group).
