Poolside began as a recording project in a converted Los Angeles backyard pool house in early 2011, producing sunny tracks of subaquatic indie dance music in this makeshift recording studio. Surfacing first in the form of a YouTube video for the catchy track "Do You Believe?" Poolside were soon gaining local and national attention, with DJs like by James Murphy of LCD Soundsystem, techno legend Derrick May, and disco don Todd Terje spinning these tracks at events and a growing online following. Throughout 2011 Poolside continued making waves with a sound called "daytime disco" through tracks like a cover of Neil Young's "Harvest Moon" as well as original tunes. In 2012 Poolside worked on a remix for longtime disco punks The Rapture and held fans over with a new single and video for a song called "Slow Down" as they prepared to release their debut album. That album, Pacific Standard Time, was released in July of 2012 on their own Day & Night label.
After the album's release, remixes for artists like Matthew Dear, Little Dragon and Fool's Gold soon followed, rehearsing and touring with a live band, and doing DJ sets around the world. Eventually, as thoughts turned to a second album, Poolside went on ice for a year; to regroup. Beginning to work in earnest on another album Fall of 2016. While still revolving around the sunny, laid-back disco sound of PST, additions of uptempo dance songs and more guitars, and generally fleshed out the arrangements with more instruments and sounds. They surprise-released Heat in June of 2017 on Day & Night.
