1st Story Renewal CD Chronicle 2nd is the remastered version of the 1st Story CD Chronicle and the last album of Sound Horizon's doujin era. It was released on March 19th, 2004 and contains 19 main tracks, 2 hidden tracks, and 6 bonus extra tracks. This album was made in response to the overwhelming request for Chronicle to be reprinted. Chronicle 2nd instead had substantial changes based on its' predecessor; adaptations being made to the lyrics, song contents, stories being added or removed, and the entire storyline being expanded upon. The world of Chronicle was reinterpreted with many songs, with some reaching over 8 minutes in length. According to Revo's blog, he stated "the power has increased by 300%!". As expected the HTML files contain additional songs and bonus tracks.
The album was originally scheduled for release in December of 2003 with 65th Comic Market but the work required to finish the album pushed back the release date. It was officially released on the internet in March and set to be sold in August of 2004 at the 66th Comic Market. Up until 2009 it was still possible to order the CD online in stock through The Tiger Cafe but it is no longer available for sale.
