Hollywood Principle was formed in 2013 by Michael Ault, Elliott Sencan, and Kayla Hope. Their music blends diverse influences to create electronic-influenced pop music. A debut single for "Find Me Out" was released in late 2014.
The group enlisted the talents of L.A.-based producer Alejandro Barajas for their debut Starting Over, released in early 2015 with the songs all concerning the five stages of loss. The singles "Firework" and "Seeing What's Next" were featured as DLC theme songs in the video game Rocket League, and were supported with a wide variety of remixes. A collaboration with local Dr. Awkward on the single "Solar Eclipses" earned more than 10 million streams on Spotify.
Their second album Colors saw the group exploring more jazz oriented harmony, heavy metal influences, and contemporary R&B sounds. After the release of the Colors: The Remixes E.P., the band parted ways with their singer Kayla Hope in 2023, leaving the duo of Michael Ault and Elliott Sencan.
