Stimmhorn is one of Switzerland's truly inventive bands. Combining natural sounds, man-made instruments, and overtone singing, the group's concerts, in churches and similar acoustically designed spaces, have been described as "technoparty or secret religious ritual." Formed in 1995, Stimmhorn represents the combined vision of multi-instrumentalist and vocalist Christian Zehnder, who combines Mongolian overtone singing and yodeling, and brass and woodwinds player Balthaser Streiff. A professional musician since 1985, Zehnder (born in 1961) studied music with Raymond Laback and Japanese philosophy with Tokne Nomaka. Alphorn, Buechel, trumpet, and cognate player, Streiff (born in 1963) is a graduate of the jazz school in Luzern. In addition to performing with Stimmhorn, he continues to teach trumpet and Alphorn. ~ Craig Harris, All Music Guide
