On October 31st, 2015, Canadians Andrew Heffernan and Ryan Paddle started creating Bass House under the name Diemetic. The duo’s debut release "Get Down" was quickly picked up by Bass Kleph/Taisun's label, Vacation Records. Diemetic’s debut 3 track EP "Natural Sweetener" was also signed to the label where it remained on their top 10 list for over a year. During this time Diemetic performed weekly at multiple venues downtown in St. John's, Newfoundland, where they started building a reputation for playing some of the heaviest bass sets in the province. The summer of 2016 featured Diemetic at a number of festivals, notably Summer Soulstice where Diemetic literally broke the main stage during their set from the high energy performance. Later that summer, Andrew and Ryan made their first ever festival appearance outside of Newfoundland at Messtival in New Brunswick.

In 2017, Diemetic followed these successes into multiple festival appearances across the Maritimes such as Future Forest, Shakedown Bass, and Backwoods Beats playing with names such as Downlink, Truth, Ill Phil, Whipped Cream and Far Too Loud. In addition, Ryan went on multiple hip-hop/rap tours across Eastern Canada with Billboard top 20 charting artist Merkules, as well as SDK member Evil Ebenezer later that year. Ryan followed this success with another two tours spanning across Europe and Canada with Merkules, Lil Windex, Evil Ebenezer and others.

Diemetic made global appearances in 2018, opening for Sullivan King and Subject 31 in Edmonton; playing on the same lineup with artists such as DJ Snake and Otto Knows at Peace & Love in Borlänge, Sweden; Curiosity Music Festival in British Columbia, and headlining in Anchorage Alaska at the annual Halloween rave, “Nocturnal”. Diemetic also performed in a multi-city tour across the Maritimes stopping in Halifax, Sydney, Moncton, and Fredericton with acts such as Far Too Loud and Pineo & Loeb. Outside of their live shows, Diemetic began working with Grammy winner Matt Stevens as well as Matt Simmers (Woofax).
