Mi Casa is a house trio or band based in Johannesburg, South Africa and consisting of three members, Dr. Duda (producer) and pianist, J'Something (vocalist and guitarist), and Mo-T (trumpeter).

The band was formed in early 2011 in Johannesburg when all three future members were at a night lounge and decided to perform together. A few months later, they released an album titled Micasa Music, which “went gold” quickly and won several awards at the 18th Annual MTN South Africa Music Awards in 2012. In 2015 they returned with their double disc album Home Sweet Home which includes hit singles Chocolate & Barman featuring Big Nuz and DJ Tira. In August 2017 they released their fourth studio album Familia after nearly disbanding four months earlier.

Mo-T’s father, Kgasoane Banza, was part of the South African Afropop band Mango Groove.

J'Something is originally from Portugal. His real name is Joao da Fonseca. He moved to Port Alfred in the Eastern Cape, South Africa when he was seven years old. He was raised by his mother Maria after his parents separated. Joao completed his bachelor’s degree in marketing at Stellenbosch University before moving to Johannesburg, where he was a studio manager at the SoulCandi Studios.

Dr. Duda is responsible for the music production for the band. He was part of a gospel band at his childhood church since the age of 8, played keyboards. He got his nickname from a FL Studio plug-in called “Duda”. He still uses DAW software, amongst others, including Cubase, Sony Acid, Reason, and Ableton Live.
