Between '98 and 2000, the four lads forged a unique sound in a variety of the city's decrepit and shady rental rehearsal rooms. Paying by the hour, they cultivated a unique aesthetic and developed their notoriously delicate and complicated creative process. In 2000, Greg and the band split leaving Daniel, Paul, and Carlos with a significant and reflective hiatus. It soon came about that Interpol would try out Samuel Fogarino, whom Daniel knew through the record store where Sam worked. Sam was perfect for the band as he gave Interpol a healthy shot of punk aggression and rhythmic backbone.
Now with the line-up revitalized, Interpol resumed gigging at venues like Brownies, Mercury Lounge, and The Bowery Ballroom. Throughout 2000 and 2001 they opened for bands like ...And You Will Know Us By The Trail of Dead, Arab Strap, and The Delgados. Then came Interpol's first release, at the end of 2000, in the form of the third installment of the FukdID EP series on Scottish label Chemikal Underground. Around the same time, the band also contributed an unreleased track, "Song Seven," to the Fierce Panda Records compilation Clooney Tunes.
Popularity abroad increased as a result of regular rotation on London's XFM. In April 2001 Interpol played in Glasgow, Manchester, and London, capping off their visit with a session for the famed John Peel. Later on in August and November, the group visited France with appearances at festivals La Route du Rock (St. Malo) and Festival Off (Paris) respectively. In November of 2001, the band tucked themselves away in Connecticut at Tarquin Studios to record their debut full-length. The album was recorded and mixed by Peter Katis (Mercury Rev, Clem Snide) and Gareth Jones (Depeche Mode, Nick Cave & the Bad Seeds, Clinic.)
In February 2011, Dave Pajo (new bassist since Dengler left) decided to leave the band. He is replaced by Brad Truax.
