Oskar Sala is a German composer mostly known for playing an old electric instrument called the Trautonium.
I found an album by him that I really like which has some nice compositions (all of them by Sala except the first track, which is by Paul Hindemith), although the instrument itself stands out more than anything else.
The download from megaupload hasn't got properly labelled tracks, but a tracklist can be found at discogs.
Not strictly a music post, but one of my posts got removed by the person it was about so I got a detailed email from Google and then started reading about that sort of stuff.
Leo Stoller is an "intellectual property entrepreneur".
