He is interested in nearly any sort of music and he likes it to find similarities between different musical genres, especially metal and classical music.
Greetings from Germany to all users of the IMSLP database :-)

Kdkeller is planning to scan and upload songs from German chant books (Gesangbücher) that are in public domain. If you have any ideas or hints please contact him.
