8 chamber rock songs with yMusic plus his Concerto for Piano and Orchestra with the Nashville Symphony conducted by Giancarlo Guerrero. In 2013, he composed "Concerto for Piano and Orchestra" to critical acclaim. Since then, Ben has continued his global symphony performance quest, recently recording a new album that features the concerto along with a host of new songs that overlap pop and classical worlds with a fresh, exciting sound he has dubbed "chamber rock".

Francis Poulenc, an accomplished pianist but little known in organ circles, published two works for organ: Litanies à la Vierge noire, FP 82 (1936), in which the organ accompanies a women’s choir, and the Concerto in G minor, FP 93 (1935–1938), with string orchestra and timpani. The latter is probably his most frequently performed and recorded concertante work, along with Concerto in D minor, FP 61 (1932), for two pianos and orchestra, and Concert champêtre, FP 49 (1927–1928), for harpsichord and orchestra. Besides Joseph Jongen’s Symphonie concertante for grand organ and orchestra, op. 81 (1926), it is the most popular 20th-century concerto among organists and audiences alike.
