The frontman of heavy metal band Lamb Of God, Randy Blythe, is back in the US after being released from a Czech prison on \$400,000 (£255,000) bail.
He was freed on the orders of a court as police continue to investigate him for allegedly pushing a fan off a stage two years ago - the young man later died of his injuries.
A Prague court dismissed a prosecution request that Blythe be banned from leaving the country. He and the band are based in Richmond, Virginia.
The 41-year-old was arrested on June 27 when he returned to the Czech Republic for another gig, not realising that he was being investigated for bodily harm resulting in death during a concert he gave in Prague in 2010.
Blythe told Czech TV that he was "relieved" to have been released, even though he had not been badly treated.
He said it had been "very tragic" that the young man had lost his life.
He added: "I feel very bad that a fan of my band is dead, that his family has to go through it. That's terrible. I feel awful for them."
Blythe, who has not been charged with a crime, insisted he was not aware of what had happened to the fan at Prague's Abaton club and had been surprised to be detained.
One theory that police are working on is that the audience member climbed on to the stage and Blythe pushed him off.
The fan hit the floor with his head and later died of his injuries. The investigation is likely to continue for some months at least.
Blythe has said he will return to Prague if called upon to do so.
One of his friends, Tommy Streat, organised vigils in support of the singer in Richmond and in Washington DC.
He urged others not to judge Blythe and the band by their stage personas or their genre, with its thrashing guitars and often dark subjects.
He said: "The Randy Blythe we know truly has not a bit of malice or ability to cause that kind of harm or take that type of action toward anybody."
And he added: "It's fantastic that he's gotten through this first step of getting the bail finalised and for everyone to realise that he's not a flight risk.
"He's an international artist who can't disappear. It's a shame it took a month for that to be agreed upon."
