Convergence features three of his sweeping works. The first is the three-part title piece performed by the Czech National Symphony Orchestra, with conductor Paul Freeman. It begins with the fast and dramatic movement "The Journey," which leads into the slow "Reminiscence in Blues," a composition that starts with the sad sound of strings, but then transitions into horns that recall a late-night jazz club. Drums then lead the movement into the final piece, a march called "La Grande Parade du Funk," a fast, drum-heavy tune that captures the enthusiasm of a parade.
The second work is the risky "River of Song," a six-part piece that was inspired by and features the poetry of children. The poems have a nature theme and specifically deal with water. This sounds like it could be a little too precious, but the section manages to avoid being overly sentimental. Brubeck and mezzo-soprano extraordinaire Frederica von Stade treat the material with care, with the lyrics serving as one layer of a more complex work. Here, the Tassajara Symphony performs, with Sara Jobin conducting. Soprano Rachel Luxon also takes part. The work ends with an E.E. Cummings poem "Maggie and Milly and Molly and May."
The third and final part is the "Prague Concerto for Bass Trombone and Orchestra." Once again, the Czech orchestra performs, with maestro Freeman at the helm. Brubeck, the son of Dave Brubeck, is the featured soloist. This section closes with the nearly 10-minute long "Dance of the Neocons," a big, splashy tour de force that showcases Brubeck’s bass trombone. At first, his hearty playing lifts and punctuates the music. About four minutes into the number, the song takes a turn, and Brubeck launches into a jazz-inspired solo before bringing the orchestra back into the fold. It’s a highlight of the CD, which Koch releases as a hybrid SACD recording.
It should be noted that despite touches of jazz, Convergence is firmly a work in classical and orchestral music.
