For the last two months, Aaron G and I have been tearing our hair out researching U2's demo recordings between 1978 - 1980. We've spoken to a number of people involved, and who were around the band back in the day. We've plowed through a number of books and other references. We've done everything we can do to make sense out of it all.
Part I is up now:

We hope you enjoy. We're putting a lot of love into the site these days and if you aren't checking out the front page from time to time you really should.
