Answer by taking a quote from the following article:

Fugazi (; foo-GAH-zee) is an American punk rock band that formed in Washington, D.C. in 1987. The band consists of guitarists and vocalists Ian MacKaye and Guy Picciotto, bassist Joe Lally and drummer Brendan Canty. Fugazi are noted for their unique sound, blending of elements of dub/reggae with high energy rock and punk/hardcore-styled guitars, as well as for their business practices and contempt towards the music industry. The band, and others from the punk and hardcore scene leading up to the early 1990s, were among the early adopters of what grew to be known as the DIY ethic.

After the hardcore punk group Minor Threat dissolved, Ian MacKaye (vocals and guitar) was active with a few short-lived groups, most notably Embrace. MacKaye decided he wanted a project that was "like The Stooges with reggae", but was wary about forming another band after Embrace's break up. MacKaye recalled, "My interests were not necessarily to be in a band, but to be with people who wanted to play music with me."  MacKaye recruited ex-Dag Nasty drummer Colin Sears and bass guitarist Joe Lally, and the trio began practicing together in September 1986. After a few months of rehearsals, Sears returned to Dag Nasty and was replaced by Brendan Canty (earlier of Rites of Spring). One day Canty's Rites of Spring bandmate Guy Picciotto dropped by during a practice session to see how his friend was getting along; he later admitted he secretly harbored the idea of joining the group. But Picciotto was disappointed that there seemed to be no place for him.  After some uncertainty from Canty about what he wanted to do with his future, the trio regrouped and booked their first show at the Wilson Center in early September 1987. The group still needed a name, so MacKaye chose the word "fugazi" from Mark Baker's Nam, a compilation of stories of Vietnam War veterans, it there being a slang acronym for "Fucked Up, Got Ambushed, Zipped In [into a body bag]".  The band began inviting Picciotto to practices. Inspired by use of a foil in hip hop, Picciotto sang backup vocals. After his band Happy Go Licky broke up, he became more involved with Fugazi. MacKaye eventually asked Picciotto to become a full member, which he accepted.  With Picciotto playing guitar full-time, Fugazi made the transition into jamming and writing new material as a band as opposed to performing songs composed solely by MacKaye. In addition to working on new material, songs they had been performing live were refined, such as "Merchandise" and "Turnover", for inclusion on their first official full-length studio album.  Released on April 19, 1990, through Dischord Records, Repeater did not initially reach the Billboard 200 charts or become a commercial success. However, the band spent most of 1990 and 1991 touring heavily behind Repeater, performing a total of 250 concerts between March 1990 and June 1991, routinely selling out 1,000-plus capacity venues throughout the world. By summer 1991, the album sold more than 300,000 copies, a large number for a label that relied on minimal promotion. While major labels began to court Fugazi, the band decided to stay with Dischord and refused the offers of those labels. Repeater ultimately went on to sell more than 1 million copies in the U.S. alone, and more than 2 million worldwide. The album was critically well received and featured an alternative rock sound that pre-dated significant releases such as Nirvana's Nevermind and Pearl Jam's Ten, which would unexpectedly go on to break the genre into the mainstream.  For Fugazi's second studio-album Steady Diet of Nothing, released in July 1991, the band once again asked Ted Niceley to produce. Niceley had become a chef and had to reluctantly turn down the job, so the band members decided to produce the record themselves. After the success of Repeater and its subsequent world tour, Steady Diet was highly anticipated, six months prior to its release Dischord had pre-orders in excess of 160,000 for the album.  Fugazi recorded its third album In on the Kill Taker in the fall of 1992 with Steve Albini in Chicago; however, the results were deemed unsatisfactory and the band re-recorded the album with Ted Niceley & Don Zientara. With the breakthrough of alternative rock in the early 1990s, In on the Kill Taker; released on June 30, 1993, became the group's first record to enter the Billboard album charts, received critical praise from Spin, TIME magazine and Rolling Stone, sold 180,000 copies in its first week of release and subsequently became the band's breakthrough album.  By the In on the Kill Taker tour, the group began to sell-out large auditoriums and arenas, as well as receive more lucrative major label offers. During the band's sold-out 3-night stint at New York City's Roseland Ballroom in September 1993, music mogul and Atlantic Records president Ahmet Ertegun met with the band backstage in an attempt to sign them. Ertegun offered the band "anything you want", their own subsidiary label and more than $10 million just to sign with Atlantic. Fugazi declined the offer. The organizers of Lollapalooza also attempted to recruit the band for a headlining slot on its 1993 tour, which the band considered but ultimately turned down.  Fugazi began writing the material for Red Medicine in late 1994, after touring in support of In on the Kill Taker. The band worked with engineer Don Zientara, but did not choose to work with producer Ted Niceley again. Fugazi opted to retreat from the in-your-face production values of In on the Kill Taker and instead worked to create an ambient sound which would display greater range and depth. To achieve this, the band handled production duties themselves, and in doing so, became more confident with in-studio experimentation. Red Medicine would take Fugazi a step further toward art rock. The band began an extensive worldwide tour in support of the album, playing a total of 172 shows between March 1995 and November 1996.
