Best known as Hieroglyphic Being, Chicago native Jamal Moss is one of electronic dance music's most fearlessly experimental artists. His futuristic, abstract compositions are influenced by free jazz, industrial, and musique concrète as well as techno and house. His recordings emphasize spontaneity and creativity over studio polish or accessibility, and he often uses analog equipment and primitive recording techniques, resulting in a rough, dirty sound. Restlessly prolific and often brilliant, he has released dozens of albums and EPs, including recordings under additional monikers such as I.B.M. and the Sun God. Some of his most notable releases include 2015's free jazz odyssey We Are Not the First (co-credited to J.I.T.U. Ahn-Sahm-Buhl), 2016's succinct The Disco's of Imhotep, and 2022's There Is No Acid in This House. Moss also runs Mathematics Recordings, which has kept Chicago's acid house legacy alive with releases by himself, Steve Poindexter, and Lil' Louis, as well as international artists such as John Heckle and EDMX (DMX Krew).

Born in 1973, Moss was a part of Chicago's acid house scene during the late '80s and early '90s. He helped create soundscapes at the Liquid Love parties at the infamous venue Powerplant, subsequently starting another event series titled Liquid Sex. From there, he came in contact with Chicago house pioneers Adonis and Steve Poindexter, who became huge inspirations to his work. Moss hosted a house program called Jack-FM on FM radio station WNUR from 1993 to 1996. That year, he started Mathematics Recordings with the release of a limited white label 12" by himself and Poindexter. He collaborated with Poindexter and Kareem Smith as Chicago Bad Boys, releasing a double 12" on Djax-Up-Beats in 1997. Along with Melvin Oliphant and Daryl Cura, he formed the Dirty Criminals and contributed to their first two releases on International Deejay Gigolo Records.

Moss' solo career started to take off around the mid-2000s. He released two EPs on Ghostly International's sublabel Spectral Sound, performed at the Detroit Electronic Music Festival in 2004, and received much acclaim from electronic music publications such as XLR8R and URB. Further releases appeared on labels such as Morphine Records, Klang Elektronik, and Dope Jams. As the 2010s began, his output became nearly impossible to keep track of, with numerous albums appearing per year, mostly as limited CD-Rs. His more experimental albums were released on labels such as Alter, Further Records, and audioMER, gaining him an audience outside of dance music circles. In 2013, Moss collaborated with Daniel Martin-McCormick (Ital) under the name Interplanetary Prophets, releasing an EP titled Zero Hour on Planet Mu. The following year, the label issued The Seer of Cosmic Visions, a compilation of tracks from Moss' limited self-released recordings. The release was credited to Hieroglyphic Being and the Configurative or Modular Me Trio.

In 2015, Hieroglyphic Being collaborated with the Sun Ra Arkestra's Marshall Allen, drummer Greg Fox, vocalist Shelley Hirsch, and several other musicians under the name J.I.T.U. Ahn-Sahm-Buhl, producing the album We Are Not the First. Issued by Rvng Intl., the record received much acclaim from the underground music press. Also that year, Soul Jazz Records reissued The Acid Documents, which was previously a limited CD-R release from 2013. In 2016, Soul Jazz issued KMT, the debut full-length by Africans with Mainframes, Moss' long-running project with Noleian Reusse. Hieroglyphic Being then released the full-length The Disco's of Imhotep on Technicolour, a Ninja Tune imprint that had previously issued his EP The Fourth Dimensions of a Nubian Mystic in 2014. Hieroglyphic Being put out his third record via Soul Jazz in 2018. Red Notes combined live instrumentation and electronic overdubs over nine tracks. Later in the year, Moog Recordings Library released The Replicant Dream Sequence, an album Moss recorded at the Moog Sound Lab UK. He also issued numerous digital-only volumes of the series The Language of Strings, as well as a double-LP of the same name. The five-track album Synth Expressionism/Rhythmic Cubism appeared in late 2019.

During the early 2020s, Moss self-released dozens of digital recordings, from raw acid to ambient experiments. Dance of the Living Image, also digital-only, was issued by Jeff Mills' Axis label in 2021. Thanks 4 the Tracks U Lost, a Jamal Moss release sharing its name with a series of digital-only Hieroglyphic Being albums, was issued by Modern Love in 2022. He also released The Shittest Sounds U Don't Ever Want 2 Hear with Spiritual Name Titles 2 Prove How Deep I Am, a double-LP of remastered tracks that included selections from yet another similarly named series. He returned to Soul Jazz with the 2022 album There Is No Acid in This House. ~ Paul Simpson, Rovi
