On the occasion of the 4th Edgar Froese Memorial Day (EFMD) on 26th January 2019 at the Ballhaus Rixdorf in Berlin, Bianca Froese-Acquaye invited Hans Joachim Roedelius, 85 years old electro pioneer of the first hour and co-founder of the legendary Berlin Zodiak Free Arts Lab (Zodiak Club) in 1969, the birth place of many Krautrock and electronic bands, even for Edgar Froese and his future band Tangerine Dream. Hans-Joachim's soulful piano playing blends in fantastically with the rhythmic beats and sounds of Paul Frick, member of the Berlin based Techno ensemble Brandt Brauer Frick, who already appeared several times as guest musician at live concerts with Tangerine Dream, and the distinctive synth sounds of Thorsten Quaeschning, long-time member and musical director of Tangerine Dream. Hoshiko Yamane, also a member of Tangerine Dream since 2011, completes the session with her extraordinary violin play by adding her special timbre we all know so well from her TD sessions. The KLANGTRAUBE is a very unique, almost meditative piece of music that invites the listener to dream. In view of the very special time in which we are all currently living in, worldwide, this piece of music reflects the spirit of the Zeitgeist very well. A piece of music for dreaming and reflection, a sound journey into another dimension, wide and intangible, like the hearts and minds that will be opened. A dignified and extraordinary session of four exceptional musicians in memory of Edgar Froese.
