Letargik is formed by Muhammad Anggara in 2011 in Melbourne, Australia. He is now based in Sydney, Australia.
In the first two years, Letargik started out as an acoustic folk project. In 2014, Muhammad started learning electronic music production and released two original songs "Commute" and "Alone". This year marked the transformation of Letargik's sound into a more synth-driven indie-pop.
In 2015, Letargik released "XXV EP", which incorporated elements of dark-techno, synthwave, and post-rock. A year after this release, Letargik released several synthwave bootlegs from various artists,
such as Bring Me the Horizon, Chromatics, and Chicane. These releases helped Letargik gained attention in the synthwave community.
In the first half of 2017, Letargik released two new singles called "Tangerine". and "Stars on the Screen". Parachute Music, an acclaimed Auckland-based music blog, positively appraised the latter song, saying '...Letargik manages to imagine what a goth M83 would sound like. His world-weary voice, soaked in reverb recalls a poetic tale of ambition and heartbreak over beautifully strident middle-of-the-night road trip beats.”
In 2020, “xxv-alternated” is released to purge all the previously unreleased and unfinished materials, making way for a new slate in 2021, when the full-length albums “Future Memories” & “Cosmic Gossip” are finally scheduled to be released to the masses.
