Recorded in the Austin homes of frontman/founder Andrew Kenny and bandmember Tom Hoff, Know By Heart features the band's signature sounds and includes fan favorites "Aaron and Maria," "The Postman," "The Kindness of Strangers" and "Choir Vandals," which was covered by Ben Gibbard for the HOME EP series split release with Kenny. Upon Know By Heart's release in '01, the album was hailed as "a soft-spoken wonder" and AmAnSet's "catchiest, most dreamy effort to date" by the Chicago Tribune while the band went on headline tours across the US and Europe, and grew to gain fellow musicians Kevin Drew, Ben Gibbard and Mark Hoppus, among others, as loyal fans.

The deluxe reissue includes never-before-seen Know By Heart-era archival photographs and liner notes, plus a download code with high-resolution MP3s of both the original studio album and 21 previously unreleased demos from the Know By Heart sessions, including 3 previously unreleased songs.
