Güenter Loibl CEO | Rebeat

Born and raised in Tulln, a small town near Vienna, Austria, Guenter Loibl is the CEO of Rebeat and founder of HD Vinyl.

Loibl founded Rebeat back in 2001. Originally, Rebeat was a distributor for CDs and DVDs in Germany and Austria. In 2006, Guenter started Rebeat Digital, a digital music distributor with a focus on artist accounting.  Rebeat Digital recognized early that digital accounting would become a critical part of the music business, due to the sheer amount of reporting data generated by streaming platforms.

In 2012, Rebeat launched MES, the first integrated distribution and accounting software solution for labels and content owners.  MES is currently the only integrated solution addressing all aspects of running a modern music label: distribution, digital accounting, mechanicals, physical accounting, analytics, etc.

In 2013, Guenter acquired Preiser Records, one of Austria’s most traditional music labels. The first release on Preiser under Rebeat was Seiler & Speer, the most successful Austrian production in decades.

Guenter has always been focused on technology and the possibilities it provides. Accordingly, his latest venture is HD Vinyl, a next general vinyl technology that offers a universal improvement to the industry’s most classic format.






David Bell BSc CEng MIoA MIET, Managing Director | White Mark Limited

After graduating from Birmingham University with an honours degree in Physics, David spent time at EMI working on the earliest digital audio projects. At the end of the 1970s, these projects culminated in the release of EMI’s first digitally mastered records for the LSO and John Williams’ band Sky.

David’s next move was to the BBC where he helped specify and design the Corporation’s first digital production facilities including the Neve-based mobile DCV. He then spent five years at Solid State Logic where he worked on algorithm development and control surface programming language creation. During this time the team created the first continuously variable digital equalisers in the world.

By the end of the 1980’s David was at Peter Gabriel’s Real World Studios, working on the musician/engineer interface of music recording and performance systems. This sparked his interest in acoustics and technical systems integration and led to a period as technical director with Harris Grant Associates. In 1997 he left to form White Mark Limited with an aspiration to bring together all aspects of technical and environmental design from the very beginning of each project so that all influences are given the correct balance from the outset. This aspiration remains the company’s key philosophy and supports every project that it undertakes.
