Hello, I would like to know who was composing that jazzy song which was used in Tenpenny tower in Fallout 3. Is there any way to download that song in better quality?. Im not interested of extracted version from bigfiles. Please just give me me some directions. God Bless the composer!

You might have better luck asking at the Bethesda forums as they developed/published the title and own the rights to that stuff.
