Kučka is Australian producer Laura Jane Lowther, whose layers of glitchy textures, found sounds, delicate beats, and vocals begin in her bedroom studio in Perth. She self-released her self-titled debut EP in 2012 and soon won praise for the experimental electro-pop sound of songs such as "Divinity," which led to the EP's re-release on New Weird Australia's label Wood and Wire. Another song from the EP, "Polly (serialkillersundays)" won a West Australian Music Song of the Year Award in the Experimental category. The following year, she released the single "Phantasy" and collaborated with A$AP Rocky, who sampled her song "I" on the title track of his debut album Long.Live.A$AP and invited her to sing backing vocals on that song and another track on the album, "Fashion Killer." She also won that year's Path to Laneway competition, which earned her a gig performing at the Laneway Festival. In 2014, she released the single "Unconditional," which earned Lowther five WAM Award nominations and wins in the Best Single, Best Experimental Act, and Best Electronic Act categories. The Unconditional EP arrived in 2015, garnering KUČKA more praise as well as more awards: Along with WAM Awards for Best Electronic Producer and Best Experimental Act, she was also invited to the Red Bull Music Academy. That year, she also collaborated with Cosmo’s Midnight on the single "Walk with Me" and appeared on songs by Seth Sentry, Andre Eremin, and Simo Soo. In 2016, Lowther issued another single from Unconditional, "Honey," and worked with Paces on the track "Nothing's Forever" and on Flume's album Skin.
