I am really enjoying this disc! Closed Mountains is a 2000 release featuring Christophe Rocher on clarinet and bass clarinet, Jean Quillivic on soprano, alto, tenor and baritone saxophone, Roman Ros on violin and guimbarde and Yuri Yaretchuk on bass clarinet, soprano and tenor saxophone. On first listen I a reminded of ROVA, if the fourth horn was replaced with the violin. Great stuff!
