Pianist Joe Haider leads a "double quartet" on this continually intriguing release. His quartet, which features the fine tenor and soprano saxophonist Thomi Geiger, is joined by the Modern String Quartet for eight originals, five by the pianist. The music is sometimes third stream and hints at modern classical music, but on other occasions is swinging jazz or a ballad with strings. The variety, the high musicianship of the players (which in spots has the strings improvising and even soloing), and the diverse moods keep this set quite stimulating. Although the European musicians are not particularly well known in the United States, jazz fans are well advised to explore this excellent set of fresh and colorful music. Scott Yanow, All Music Guide
