Electro-Swing Houe set played live at Frolic Campout in July 2012. 

LeftCtrl Live at Frolic Pondside, 2012

LeftCtrl —(also known as PolyGroovers, or DJ Zeel, real name: Konstantin Gredeskoul) started DJ-ing in the Bay Area in 1998, having been inspired and encouraged by @djethan Ethan Miller (FnF, BrassTax) among others. 

Konstantin produces downtempo music as PolyGroovers, (see https://soundcloud.com/polygroovers for more information).

Starting with the underground rave parties where he threw down Detroit Techno on vinyl, LeftCtrl played all over the Bay Area, with additional appearances in the UK, Spain, and Australia. 

He collaborated with @kem, Captain Tinrib, @henry-navarro and many more.

LeftCtrl's DJ sets feature a storyline, harmonic depth, and a smooth and deep, melodic, nearly always syncopated and groovy sound. Konstantin is an obsessively technical mixer, who admits to the most anal-retentive pitch-matching of the mixes, resulting in some of his entire sets played in the same key.

Since about. 2020, LeftCtrl refocused on the composition and production of tracks for the dance floor: house, progressive, and many genre bending tracks. Currently collecting sufficient portfolio for the upcoming releases in yet to be determined label.
