Welcome to the forum! I agree that Heinrich is a fascinating figure-he was way ahead of his time for a composer whose dates were 1781-1861. There is certainly a similarity between his music and Berlioz's in its non-conformity and eccentricity. He composed no less than 14 symphonies, none of which follow tradition symphonic form and which often have fanciful titles (see a list of them here:
http://www.musicweb-international.com/Ntl_discogs/American_Symphonies/american_symphonies1.htm). I never knew CPO had any interest in him-I'm not getting my hopes up for a release (knowing CPO's erratic release schedule), but I'll keep an eye out for any further developments. I see there are three of his orchestral pieces on YouTube (besides
The Orinithological Combat of Kings, which is already available on a New World disc)-the two you mentioned in your post plus the Capriccio
The war of the elements and the thundering of the Niagra. Such wordy titles remind one of the subtitles of Rued Langgaard's (a similarly eccentric composer) symphonies ;D
