The VibysM is a 3 1/2 octaves Musser concert vibraphone. This is one of the best vibraphone models ever made.
During the recording session, it was played with soft malets in order to capture the most of the dynamic range and the softness of this particular instrument. The Vibraphone was very popular in the Jazz music of the 50’s only to then fall into disuse.
Today it is used more and more in popular music as well as modern jazz and even electronic music.
