The Prodigy front man Keith Flint has died aged 49.
Instantly recognisable for his fluorescent spiked hair and incendiary performances, the musician sang lead vocals on both the band's number one singles, Breathe and Firestarter.
He was found dead at his home in Dunmow, Essex, on Monday morning, reports BBC.
The band, who were due to tour the US in May, confirmed his death in a statement, remembering Flint as a "true pioneer, innovator and legend".
In a post on The Prodigy's official Instagram account, bandmate Liam added: "I can't believe I'm saying this but our brother Keith took his own life over the weekend.
"I'm shell-shocked, angry, confused and heart broken."
Pioneer
Fans and friends flooded Twitter with tributes as news of the star's death spread.
The Chemical Brothers' Ed Simons remembered him as "a great man" who was "always great fun to be around".
Radio 2 DJ Jo Whiley described Flint as "an absolute sweetheart" and "iconic frontman"; and dance duo Chase & Status said: "We wouldn't be here if it wasn't for Keith and the life changing music they made and championed."
The Prodigy were the most successful band to emerge from the acid house scene of the late 1980s.
They met at an open-air rave in 1989; where Flint approached DJ Liam Howlett and asked him to make a mixtape for him.
Labelled Prodigy after Howlett's favourite synthesizer, the tape went down so well that Flint encouraged Howlett to pursue music professionally, offering up his services as a dancer.
Along with Leeroy Thornhill, they scored early hits with Everybody In The Place, Out Of Space and Charly - which sampled the dialogue from an old children's safety film: "Always tell your mummy before you go off somewhere."
Their music matured on their second album, Music For The Jilted Generation, which saw Howlett incorporate breakbeats, guitar loops and hip-hop samples on tracks like No Good (Start The Dance) and Voodoo People.
The album was nominated for a Mercury Music Prize - but the band truly went global when Flint grabbed the mic and unleashed the full fury of his voice on the abrasive, in-your-face rave-rock anthem Firestarter.
It knocked Take That's How Deep Is Your Love off the top of the charts in 1996, selling more than 600,000 copies in the UK alone.
Spurred by its success, the band's third album, Fat of The Land, went to number one in both the US and UK, selling several million copies worldwide.
Flint stepped up as a frontman, giving The Prodigy a demonic focal point for their live shows - including a notable headline slot at Glastonbury in 1997.
The cause of his death is unknown.
In a statement, Essex police said: "We were called to concerns for the welfare of a man at an address in Brook Hill, North End, just after 8.10am on Monday, March 4.
"We attended and, sadly, a 49-year-old man was pronounced dead at the scene. His next of kin have been informed.
"The death is not being treated as suspicious and a file will be prepared for the coroner
