The trombonist Roswell Rudd, is primarily known for his music in free and avant-garde jazz and has worked extensively with saxophonist Archie Shepp since 1962.
In 2001 Rudd and his producer and partner Verna Gillis of Soundscape, traveled to Mali to produce his album MALIcool, a cross-cultural collaboration with kora player Toumani Diabaté and other Malian musicians. This was the first time a trombone had been featured in a recording of Malian traditional music.
In 2004, he brought his Trombone Shout Band to perform at the 4th Festival au Désert in Essakane, Tombouctou Region, Mali. In 2005, he extended his reach further, recording an album with the Mongolian Buryat Band, a traditional music group of musicians from Mongolia and Buryatia, entitled Blue Mongo.
Here his interpretation of Tuning Score for the Nervous System uses techniques to elicit unconventional and transformative sounds and utterances from his trombone to create a kind of energy music.
