Hey, so I like to think of myself as relatively computer savvy, but it never occurred to me to try looking for Gary Hansen's lost Charlie Christian website using the Internet Archive... until this morning. It occurred to me because the other GREAT Charlie Christian website, Leo Valdes's Solo Flight, has now disappeared.
So, may I present to you... working links for the internet's two best sources of Charlie Christian content, and two sites that were absurldy important for my development as a Swing Guitar player:
Gary Hansen's Charlie Christian Site (via web.archive.org) - featuring many transcriptions in both notes and tab, and lessons on the "geometric" pattern-based playing of Charlie Christian
Leo Valdes's Solo Flight (via web.archive.org) - featuring many transcriptions and other resources, most notable for it's alternative theories on Charlie's fingerings of certain patters. Some of them make perfect sense, others not so much. Still, it's a valueable resource.
