Marumaru, real name Avery Hutley (born July 6, 1993 in Sydney), is an Australian electronic music producer, songwriter, comedian, and manga translator who now lives in Kyoto. She releases music under several names: marumaru, Cherax Destructor (CxDr), ᴅᴀɪᴋᴜ ɪɴᴅᴜsᴛʀɪᴇs, helpful kappa, and lucky beast. She is also a member of the Australian pop‑rock band Dr. Spaceman.

Her music blends many styles, including IDM, friendship-hop, breakcore, glitch, ambient, acoustic, alternative, and folktronica. She uses vocals, guitar, piano, synthesizer, euphonium, trombone, and works with a DAW and sampler.

Hutley grew up in Sydney and joined her school’s concert band in third grade, learning euphonium and piano. She later wished she had started sooner. Her first electronic inspiration came from a friend, Luke Midworth, and she began making electronic music after discovering Ableton Live through him.

Cherax Destructor is described as folktronica or friendship-hop, with comparisons to Baths. Helpful kappa is her post-rock project, influenced by Sigur Rós and Explosions in the Sky. ᴅᴀɪᴋᴜ ɪɴᴅᴜsᴛʀɪᴇs is her breakcore/bass music project, inspired by Yoko Kanno and Hiroyuki Sawano.

In 2013, her track <3 from the album Amity Lines was praised by Under the Radar for its joyful, chopped-up melodies, and she was credited with pioneering the ‘friendship-hop’ style by BULLSH!T. The track <3 was also played on 2SER in a feature about emerging Australian musicians.

She headlined AVCon’s JOYPAD after-dark in 2015, where organizers described her as a conflicted soul whose music fuses her passions into something weird and wonderful.
