[1] Born in 1992 in San Diego, Kiefer started playing piano around age six, and was first introduced to jazz by his father.
Growing up, he took classical and jazz lessons, and by his teens was an adept soloist and began experimenting with producing his own computer-based hip-hop and electronic beats.
That same year, he released his debut album Kickinit Alone, on Leaving Records, where the title track was described as a 'short piano phrase looping like it was ripped from a dusty vinyl and brought to life' by Pitchfork.
In March 2021, Kiefer released two singles – Superhero and Friends – before dropping the last instalment in the trilogy of EPs, Between Days, on Stones Throw.
He is also a fixture in Mndsgn's live setup, and has made beats with Kaytranada, and played with Terrace Martin, Moses Sumney, among others.
