[citation needed] On this first tour they sold an untitled demo tape, which consisted of the four Kanker Sores songs recorded in 1997 for the split release with Treadwell.

This reunited all four surviving members from Kanker Sores, and formed the core of The Icarus Line's lineup as it existed for many years, minus the "revolving door" of drummers.

1999 saw the band release a split 7-inch with Ink & Dagger, followed shortly by the "Kill Cupid With A Nail File" single on Buddyhead.

2000 found the band finally recording their debut album, Mono, across different sessions with Mark Trombino and Alex Newport.

[citation needed] In 2001, the band embarked on an eight-week tour of Europe, and the "Feed A Cat To Your Cobra" single was released in the UK.

Two John Peel sessions were recorded, the first while The Icarus Line were in the UK on a two-month tour, and the second while playing the Reading Festival in the summer of 2002.

The Icarus Line's sixth drummer, Troy Petrey, left the band and Jeff "The Captain" Watson returned.

In August 2011, the band released the album Wildlife, characterized by the greater prominence of frontman Joe Cardamone, who, in addition to lead singer and primary songwriter duties, further expanded his responsibilities to include producing and engineering.

Annie Hardy from Giant Drag is featured on several of the tracks on Wildlife, and also appeared on organ for some of the Los Angeles live performances surrounding the record release.

[citation needed] In late 2012, Joe Cardamone, Alvin DeGuzman, Lance Arnao and Ben Hallet began the writing process for the next yet-to-be-titled full-length LP.

After DeGuzman was diagnosed with cancer, and becoming disillusioned by touring with Scott Weiland, Cardamone quietly left the group at the end of 2015, pursuing a solo career.
