Originally from Quedlinburg, Germany, Ring relocated to Berlin in 1997. Around 2000, he began to help run experimental techno label Shitkatapult along with its founder, Marco Haas (T.Raumschmiere). Apparat's debut full-length, Multifunktionsebene, was released by the label in 2001, with the limited EP Algorhythm appearing on the Jetlag imprint soon afterwards. Shitkatapult then released 2002's Tttrial and Eror EP, followed by second Apparat full-length Duplex in 2003. While just as tense and noisy as Ring's previous releases, the album introduced guitars and woodwinds to his sound, as well as the occasional presence of vocals. During the same year, Ring contributed to Ellen Allien's acclaimed Berlinette album, and released the more club-oriented Koax EP on her BPitch Control label. The abstractly funky Can't Computerize It followed on the same label in 2004, while Shapemodes, a more cerebral EP recorded several years earlier, appeared on Neo Ouija.
Apparat's 2005 EP Silizium, containing reworked material from his 2004 Peel Session, melded indie rock-inspired vocals and warm guitars with glitchy electronics. Ring returned to more dancefloor-primed material with 2006's Berlin, Montreal, Tel Aviv EP (excerpted from live gigs at each respective city), followed swiftly by Allien collaboration Orchestra of Bubbles, which blended elements of rave, dubstep, and electro. The enormously well-received album was followed by Apparat's third solo album, Walls, in 2007. Ring began touring with a live band that included Raz Ohara on piano and drummer Jörg Waehner. In 2008, Apparat guested on Luomo's single "Love You All" and released Things to Be Frickled, a double-CD collection of remixes. Ring also left Shitkatapult in order to devote more time to his music.
2009 saw the release of Moderat, the self-titled debut full-length by Ring's collaboration with Modeselektor, which had previously released an EP in 2003. More accessible than either act's previous work, the album was an indie crossover hit, and Moderat became a popular live draw, with the readers of Resident Advisor voting the supergroup the best live act of the year. In 2010, Apparat released his first mix CD, a volume of !K7's long-running DJ-Kicks series, before signing to Mute and releasing the more downtempo full-length The Devil's Walk in 2011. Krieg und Frieden (Music for Theatre), based on a score for a theatrical production of War and Peace, followed in 2013.
Ring then put his solo career on hold as he focused on his work with Moderat. II was issued on Modeselektor's Monkeytown label (and Mute in North America) in 2013. After three years of extensive touring, Moderat released III in 2016, with Live appearing at the end of the year. The trio announced their indefinite hiatus following the conclusion of their world tour, which wrapped up in Berlin in September 2017. Apparat and Philipp Thimm co-wrote the score to the 2018 historical drama Capri-Revolution, which won Best Soundtrack at the Venice Film Festival. Thimm then contributed strings to Apparat's Grammy-nominated LP5, which appeared in 2019. ~ Paul Simpson, Rovi
