Klaus Wiese (1942-2009) was a German musician and sound researcher. Wiese brought the teachings of Sufi Hazrat Inayat Khan to Germany from his travels in the East. His album "El-Hadra, the Mystik Dance," which he created with Mathias Grassow and Ted de Jong, made him famous in the genre. Under his own name, From 1981 until his unexpected death in 2009 he released upwards of 60 recordings, not including collaborations (with Oophoi, Mathias Grassow, Ted de Jong, Jim Cole, Al Gromer Khan... to name a few). Wiese's music exists at the nexus of several overlapping modes - ritual, dark ambient, environmental - yet new age exerted an influence as well, most audibly on these late 1980s outings. On his recordings, Wiese used Persian stringed instruments, Tibetan singing bowls, bells, voice, and other exotic instruments. "Qumra" duology was released in 1986 and 1987 by a German label Aquamarin Verlag and reissued on small run CD-r by Gianluigi Gasparetti (Oöphoi) on his own label Umbra. Since then both parts became extremely rare items and top-wanted albums for searchers of spiritual ambient music. "Qumra II" was included in the 20 best new age albums ever recorded, by FACT magazine. "Qumra" is one of the most beautiful ambient recordings I have ever heard. A sweet stream of otherworldly music dissolves time and space and brings you to a place of perfect and endless tranquility.
