Deletion of David J. Sosnowski

Comment: I've failed to find any mention of him or his work in reliable independent sources, let alone in-depth or significant coverage. CDs and scores are self-published, and observe the upper left hand side of http://davidsosnowski.com/ his website. Below his one-sentence 'biography' we find: ''"See the Wikipedia article David J. Sosnowski|here for more on David Sosnowski."'' Comprehensively fails the criteria at  and  and blatant self-promotion
