Seems strange that some of his modules were credited, but many more weren't, presumably being compo entries?
As Saga said, one hour compos are fully informal and the authors rarely "officially" release the tracks due to the fact that very few people are able to pull off anything they're satisfied with within an hour. If you want to collect one hour compo tracks, it's fine, but it would be somewhat ill-mannered to release the tracks publicly in behalf of the authors, which is why you will rarely find them from the bigger mod music archives, especially properly credited.
Everything after that is on s3m.it - since all #mod_shrine / #modulez compos have been running on that site.
Oh, looks like compos are still happening. Maybe I return one day.
