An almost forgotten German composer, Kreutzer was born in 1780 and like Beethoven, studied under Albrechtsberger in Vienna. He is believed to have been the last pupil of Joseph Haydn. He died in Riga in 1848.
I have been listening to two of his pieces all week. Opus 62 is a septet and opus 43 a piano trio. The CD I have features the Mithras Octet (of the Broadcasting Corporation of Saarland) with Paul Rivinius on piano.
The music is delightful. If you can get hold of the disc I recommend it.
