There are at least two symphonies by Loewe – one, in D minor, has been recorded on the Koch Schwann label together with the first of at least two CD recordings of Loewe's second piano concerto (in A major), and another, in E minor, was given its first performance in 170 years in November 2004. (The cpo series of recordings of Loewe's complete ballads includes as well a recording of two piano sonatas and a "tone poem in sonata form", with one of the sonatas – the E major of 1829 – having a vocal part for soprano and baritone.)
