It ranked 43 weeks in the top 10, a total topped by only one country album in history, "Ropin' the Wind" by Garth Brooks.

It was released on January 23, 2008 through Victor Entertainment's BabeStar Label.  The album primarily features music written by vocalist Ichiro Yamaguchi since the release of their debut album "Go to the Future" (2007).  Compared to their debut album, which compiled songs that the band had already written, the majority of the songs on "Night Fishing" were written specifically for the release.  The album was an attempt by the band to find a better balance between popular music and underground, and was an album where the members wanted to incorporate more of their own personal styles; which caused the members to disagree over its content much more than on their debut album.

Periphery is the debut studio album by American progressive metal band Periphery, signed by Sumerian Records and released on April 20, 2010.  Many songs on the track list had been written long before the release date but due to vocalist complications the debut album had been postponed on several occasions.  Former vocalist Chris Barretto had nearly finished recording the album before he and the band parted ways months before its release.  Rather than release the songs with Barretto's vocals, the band decided to rerecord Barretto's songs with Spencer Sotelo; however, Sotelo only re-worked a few of the melodies when recording vocals, versus writing completely new lyrics.  As a result, Sabol's and Barretto's lyrics and vocal melodies and harmonies are still featured on the record.  The album was re-released on February 6, 2012 as a 'Special Edition' including instrumentals, along with a new song "Passenger," originally recorded by guitarist Mark Holcomb during his time in the band Haunted Shores.
