Initially influenced by disco, R&B, and electro producers like Jam Lewis and Arthur Baker when he first started to DJ during the '80s, Rachmad became enamored of the Detroit techno and Chicago house sounds that began making waves later in the decade. He started releasing material under names like Rachmad Project and A Scorpion's Dream by 1993, premiering his Sterac moniker with the EP Sitting on Clouds, issued by 100% Pure in 1994. Full-length Secret Life of Machines and EP Asphyx appeared in 1995; both releases subsequently became regarded as techno classics. Several additional 12"s preceded the second Sterac LP, Thera, which appeared in 1998. "Skreel-Ah" came out on Robert Hood's M-Plant in 1999, and an untitled EP was issued by Tresor in 2000. Hong Kong-based Sino released the single "Sinosphere" in 2001. Rachmad began releasing electro-funk as Sterac Electronics starting with the 2002 EP My Preparation. Music Man Records' Ion sublabel issued the Sterac EPs More or Less (2004) and Heaven's Mouth (2005), and Rond Bot appeared on Delsin in 2008.
In 2012, 100% Pure released a remastered and remixed edition of Secret Life of Machines, with some of the tracks rearranged at slightly slower tempos for greater DJ accessibility. A series of EPs featuring remixes by producers like Ricardo Villalobos and Heiko Laux were also issued. Klockworks 12 (for Ben Klock's label) and The Hypnoticus (on Delsin) both appeared in 2014, and Different Strokes was released by Mote-Evolver in 2015. Scorp, a collection of Rachmad's early 2000s material under the same name, was issued (as a Sterac album) by Token in 2016. A full-length by the long-dormant Sterac Electronics moniker, Things to Think About, appeared on Tom Trago's Voyage Direct label in 2017. Two Sterac EPs, 11 (Kanzleramt) and Aeras (Indigo Aera), both appeared in 2019. Numbers surfaced in 2021, and 2022 brought Missing Secrets and Light in the Darkness. ~ Paul Simpson, Rovi
