When Åhr was a teenager, he called himself a loner who made a majority of his friends online. Inspired by underground acts like Seshhollowaterboyz and iLoveMakonnen, Åhr left high school early to move to Los Angeles and meet up with online friends. Initially living in Skidrow, Los Angeles and dipping in and out of homelessness, he eventually met up with Memphis producer JGRXXN and Florida rappers Ghostemane and Craig Xen, living with them while forming the collective Schemaposse. According to Åhr, he originally met Craig Xen online and was introduced to JGRXXN who needed a singer. Åhr also attempted to attend Glendale Community College during his first year living in Los Angeles.
In 2015, Åhr released his first mixtape, Lil Peep Part One, which generated 4,000 plays in its first week. Shortly thereafter, he released his first extended play, Feelz, and another mixtape, Live Forever. Åhr began to grow in popularity soon after, with the song "Star Shopping" (later released as a single following his death) from Lil Peep Part One making waves in underground hip-hop circles. Åhr's popularity continued to grow after the release of the song "Beamer Boy" which led to him performing live for the first time with the rest of Schemaposse in March 2016 in Tucson, Arizona. The following month, Schemaposse broke up and Åhr wasn't associated with any collective though they remained on good terms.
Shortly after the breakup of Schemaposse, Åhr began to associate with Los Angeles-based rap collective, Gothboiclique, featuring members of the group on his full-length mixtape Crybaby. According to Åhr, Crybaby was recorded within the space of three days with an $150 microphone. He did a majority of the mixing and mastering himself. Crybaby was released in June 2016.
In September 2016, Åhr released Hellboy. Songs from Hellboy such as "Girls" and "OMFG" began to clock in millions of views and plays on SoundCloud and YouTube.
In May 2017, the band Mineral accused Peep of copyright infringement for including an unlicensed and uncredited sample of their song "LoveLetterTypewriter" in his "Hollywood Dreaming" track. Peep said that he was only trying to "show some love" with the sample. One month later, Peep announced his debut album, Come Over When You're Sober, via Instagram. The album was given the release date of August 11, 2017. After a slight delay, the album was released on August 15, 2017. Peep announced a Come Over When You're Sober tour to promote the album. The tour began on August 2, 2017, and was scheduled to end on November 17, 2017, but was cut short by two days due to his death.
Lil Peep was described as making lo-fi rap,being an "emo-trap heartthrob" and an "emo rapper". New York Times music critic Jon Caramanica defined Peep as the Kurt Cobain of lo-fi rap and described his music as gloomy and diabolically melodic. Peep's music generally drew on both Southern rap and the angsty introspection of the rock subgenre post-hardcore. He said that he wanted to become the "New Kurt Cobain". AllMusic described his music as a blend of hip hop and rock influences along with trap, punk, and dream pop.
Peep's music contains lyrical themes regarding topics such as depression, drug use, past relationships, and suicidal thoughts. He had been described as the future of emo by Steven J. Horowitz of online magazine Pitchfork. Before the release of his first album, he mentioned Kurt Cobain, David Bowie, Frank Ocean and Riff Raff as inspirations, and wanted to be known as the "Kurt Cobain of Rap". His other musical influences include Gucci Mane, Red Hot Chili Peppers, Crystal Castles, Seshollowaterboyz, Rozz Dyliams, My Chemical Romance and Panic! at the Disco. His songs have sampled such artists as Blink-182, Pierce the Veil, Brand New, Radiohead, Underoath, Three Days Grace, Avenged Sevenfold, Slayer, The Postal Service, Oasis and The Microphones.
Following Åhr's death, the single "Awful Things" from Come Over When You're Sober, Part One charted, becoming his first and only entry on the Billboard Hot 100 at number 79.
