Legacy
Several publications have commented on the musical legacy Bennington left behind. While describing the success of Bennington and Linkin Park, AllMusic's Andrew Leahey said, "Although rooted in alternative metal, Linkin Park became one of the most successful acts of the 2000s by welcoming elements of hip-hop, modern rock, and atmospheric electronica into their music ...focusing as much on the vocal interplay between singer Chester Bennington and rapper Mike Shinoda." Writing for Billboard, Dan Weiss stated that Bennington "turned nu-metal universal", as he was "clearly an important conduit for his far-ranging audience".
Fred Durst stated that if it were not for Bennington's voice and his words, nu metal "would never have reached the masses and affected so many lives".
The New York Times' Jon Caramanica commented that Bennington's ability to "pair serrated rawness with sleek melody" separated him from other contemporary singers, and also from the artists he was influenced by. Caramanica noted, "He was an emo sympathizer in a time when heavy metal was still setting the agenda for mainstream hard rock, and a hip-hop enthusiast who found ways to make hip-hop-informed music that benefited from his very un-hip-hop skill set." As Bennington acquired influences from industrial and hardcore punk acts, the journalist believed this was the factor that made Linkin Park survive the "rise and precipitous fall of the rap-rock era", calling the musician "a rock music polymath". Mikael Wood of the Los Angeles Times argued, "Perhaps more than Linkin Park's influential sound, Bennington's real artistic legacy will be the message he put across – the reassurance he offered from the dark."
BBC's Steve Holden called Bennington the "voice of a generation", saying his voice was arguably Linkin Park's greatest asset. Jonathan McAloon of The Daily Telegraph commented, "Bennington's death will have an impact on many millennials because his voice was the sound of their millennium." While talking about Linkin Park's popularity, Corey Apar, of AllMusic, commented, "Bennington's oft-tortured vocals became one of the most distinctive in the alternative rock scene." Writing for the Guardian, Ben Beaumont-Thomas noted, "Bennington's decision to sing clearly and openly was, therefore, more radical than he is given credit for, and indeed more socially valuable." The journalist continued to discuss Bennington's impact, commenting,
His cleanly articulated tales of emotional struggle gave millions the sense that someone understood them, and the huge sound of his band around him magnified that sense, moving listeners from the psychic space of their bedrooms into an arena of thousands of people who shared their pain.
James Hingle echoed this sentiment, writing for Kerrang!, "[Bennington] was one of the most honest vocalists out there when it came to his mental health". In the same topic, William Goodman from Billboard said Bennington and fellow musicians Chris Cornell and Scott Weiland "helped define a generation of the hard rock sound, who were tied together artistically and personally".
The Straits Times' music correspondent Eddino Abdul Hadi stated Bennington was an inspiration to many artists in the Singapore music scene. Calum Slingerland, editor of the Canadian periodical Exclaim!, expressed, "[H]is influence has been felt in the worlds of rock, metal, rap, and beyond."
After Bennington's death, his widow Talinda Bennington launched a campaign called 320 Changes Direction in honor of her husband to help break the stigma surrounding mental illness.
In 2020, during a Twitch live-stream, Mike Shinoda confirmed the existence of an unreleased Linkin Park song, titled "Friendly Fire", which features vocal tracks Bennington recorded during the One More Light sessions. The song was released on February 23, 2024. At the time of his death, Bennington just finished a collaboration with Lamb of God guitarist Mark Morton for Morton's solo album Anesthetic entitled "Cross Off"; Morton later said in interviews that Bennington was "very, very excited about the idea of screaming and doing something heavier than what he's been doing lately". The music video for "Cross Off" later featured an empty microphone as a tribute to Bennington.
During an interview with Zane Lowe in 2024, Bennington's successor in Linkin Park, Emily Armstrong, called the band's debut album Hybrid Theory her favorite album and specifically cited Bennington's performance in the song "One Step Closer" as her inspiration to be a singer, commenting, "That was the moment I was like, 'I want to sing and scream', you know? 'One Step Closer', I was like, 'I could do that'. At the time I wasn't even a good singer. I was a guitar player in a band, you know? . . . And obviously, on the side of the feelings and the emotions of it, like, I would love to do him proud."
In 2025, Stephen Andrew Galiher of Vice included him in his list of "4 Metal Vocalists Who Mastered Both Screaming and Singing".
