Horst Weidenmüller

In 2017, Weidenmueller created a classical music label 7K!, and signed several composers and musicians from the neoclassical genre, including Luca D'Alberto, Niklas Paschburg and Henrik Schwarz. Weidenmueller was the Executive Producer on Endless, D'Alberto's 2017 album. He was also Creative Director on Paschburg's 2018 album, Oceanic. In 2019, Weidenmüller created Ever Records, a jazz label, and signed musicians such as the Kansas Smitty's House Band.

In 2008, Weidenmüller acquired Strut Records and relaunched the label under the !K7. In the early 2010s, he started an artists management division and signed on to manage the rapper Tricky. Tricky wrote in his biography, Hell Is Around The Corner (2019), how Weidenmüller helped him rectify his finances and build a new catalogue of music for which he retained the rights.! K7 Management also began representing Mykki Blanco, DJ Tennis [de], Brandt Brauer Frick, Marquis Hawkes, and Portable.

He has served on the board of several associations representing independent artists and record labels. He has served on the board of directors of the IMPALA since 2003. He joined the executive team at IMPALA in 2006 and served as co-president until 2011. Since its founding in 2008, Weidenmüller has also been on the board of Merlin Network, the largest organization representing independent digital rights holders.

Weidenmüller became an influential part of the Berlin techno music industry in the early 1990s. In 1993, he released his first X-Mix [de] video cassette. These remix videos combined DJ mixes with computer animation for at-home viewing. In the mid-1990s, X-Mix videos, including those of Laurent Garnier or Richie Hawtin, were aired at night on MTV. X-Mix became a platform by which artists working in computer graphics could showcase their nascent art form. As Germany was reunified, techno had become popular in both East and West Germany and, according to the German magazine Der Spiegel, "X-Mix gave techno a face", bringing it out of the dark basement venues where it initiated. Weidenmüller also started DJ-Kicks, a DJ mix series first released in 1993, which released its 72nd edition in August 2020.

Weidenmüller founded Studio !K7 (now known as !K7 Music) in 1985 in Berlin at the age of 21. It was located at Kaiserdamm 7, an address that became the inspiration for the company's name. Initially, Weidenmüller focused on creating concert videos for punk bands which were shown in cafes, such as Café Swing [de] in Berlin, before the advent of music videos on television. He produced live video footage of concerts by Nick Cave, Einstürzende Neubauten, Crime & the City Solution, and Lydia Lunch.

Weidenmüller was born in the Black Forest region of West Germany. He moved to Berlin in 1982.
