Given the following context:

In 1997, the Strokes consisted of singer Julian Casablancas, guitarist Nick Valensi, bassist Nikolai Fraiture, and drummer Fabrizio Moretti. Casablancas's stepfather and Moretti's and Fraiture's older brothers introduced the quartet to the music of reggae artist Bob Marley, protopunk group the Velvet Underground, and alternative rock band Jane's Addiction. Discussing the formative stages of the group, Moretti noted, "Our music was, like, [the Doors'], but trying to be classical. We all took music classes and tried writing songs, and when we put them together they were this crazy amalgam of insane ideas that we thought was really cool." In 1998, Albert Hammond, Jr., who Casablancas knew from his time at a Swiss boarding school, moved to New York City to attend film school and joined The Strokes as a second guitarist. His arrival provided the catalyst for the band's musical and emotional evolution.By 2000, all band members had part-time jobs and were practicing new material several nights a week in a small hired recording space. In the fall of that year, their demo caught the attention of Ryan Gentles, a talent booker at New York City's Mercury Lounge. He scheduled the Strokes for four December gigs. With support from personal mentor JP Bowersock and producer Gordon Raphael, the band recorded three tracks which later appeared on Is This It: "The Modern Age", "Last Nite", and "Barely Legal". British label Rough Trade Records was impressed by the songs and released them as a January 2001 extended play titled The Modern Age. Music press reaction was very positive and the Strokes embarked on a sold-out UK tour, followed by US support slots for alternative rock groups Doves and Guided by Voices. Gentles quit his job to manage the band full-time and, in March 2001, the Strokes signed to RCA Records after a protracted bidding war.
