The Quick Brown Fox (often shortened to TQBF) is an alias of em essex producing upbeat speedcore and gabber. They first released a self-titled debut album in May 2008 under the VULPvibe Records label, which later rebranded to LapFox Trax and later in conjunction with Halley Labs.

The Quick Brown Fox is portrayed as an anthropomorphic fox-shaped piñata (a play on “beats per minute”). Musically, They are recognized mostly for their staccato synth lines and very fast tempos, ranging from approximately 200 beats per minute up to and over 1000 beats per minute.

Em says that the original driving force to start the project was inspiration from m1dy’s speedcore productions and the generally upbeat or non-serious tone, which tends to be a stark contrast against speedcore’s generally serious and angry tone. As such, TQBF is often regarded as a good entry point for speedcore, as it is accessible, if not through melodic content, then through comedic.

TQBF’s fictional character profile reads:

a piñata that was animated through unknown means. just kidding. TQBF is a series of experimental projects with the goal of building a resilient, thin robotic shell. initally lacking personality, an increasingly complex neural network has been built for these projects. at some point it was given the ability to speak, though only through a port of Software Automatic Mouth. it is unknown what iteration of TQBF is currently active, and they all differ in slight ways. at some point, the network developed a strong fondness for BANDETTO.
