Tomaga co-member Valentina Magaletti has confirmed the news that the London based duo’s Tom Relleen died of stomach cancer in London’s St Bartholomew's Hospital on 23 August.

Founded in 2013, Tomaga released a number of albums through the Hands In The Dark and Meakusma labels. The duo also collaborated with Pierre Bastien on Nicolas Jaar's Other People label and released a split 7" with Charles Hayward on God Unknown. According to The Quietus, Tomaga had scheduled another release for 2020. "We rushed to master the album in his final days because the release was important to him," confirmed Magaletti.

In 2017 Tomaga put together an hour-long mix for The Wire, featuring artists Marc Barreca, Charles Hayward, Pancrace and others.
