Iconic garage rockers Iggy and The Stooges released their latest studio album Ready To Die nine days after Iggy Pop turned 66.
And while the singer looks like he's 66 going on 27 physically, Pop says singing the new material was challenging.
"Honestly it was a stretch for me to sing with a loud and at times violent rock band which is sort of what the band has matured into," he says from a Berlin hotel.
"When my own life has become a little farther flung than that and my last two albums was singing everything from Autumn Leaves to Serge Gainsbourg songs. But I noticed it connect with certain people in certain ways but it was difficult for me."
The group - co-headlining Riotfest Sunday night in Toronto with The Replacements - underwent changes after guitarist Ron Asheton died in 2009 and was replaced by former Stooges guitarist James Williamson.
It was Williamson who brought Pop the music for the song Unfriendly World about a relationship's demise. Meanwhile the title track paints a darker world teenagers encounter today growing up.
"I tried to bridge the gap between the depression of living the way we do and the anger and desperate fear a young person would feel about that," he says.
"I feel personally since Columbine and right on through with a lot of the violent incidents in North America particularly that a lot of it is prompted by an over-regimented, over-built, overpaid, over-hyped society."
Pop says the shows this year have been "terrific" with the set mixing new tunes with classics from Raw Power, Fun House and Kill City among others.
"Touring is hard work and I won't kid you, we put a lot into it but it's just been, really, really good," he says. "We're really f---ing good! I don't usually like bragging but we're good."
But these 2013 shows might be the last for a little while for Pop. He's curtailed his stage dives somewhat after a 2012 Barcelona incident left a mark.
"I was irritated about something and I wanted to make an impression so I unwisely tried to do a stage dive off a 10-foot stage," he says.
"I cracked skulls with some bald guy. There was a lot of blood and I had to have stitches over my eye."
Our phone conversation with Pop also coincides with the fact it was 44 years ago to the day The Stooges self-titled debut was released in the U.S.
"Oh I didn't know that!" he says. "Yeah it was August, I walked to the record store every Tuesday, they'd put out the new albums in the window. So I walked every Tuesday for two months waiting for that to come out. And then one day, 'Hey I'm in the window!'"
Finally, what would Ron Asheton have thought of the new record?
"Well he would've hated it because James was on it," Pop says. "This is a competition, severe competition is a given when you're dealing with a job with extreme rewards. This is not f---ing McDonald's you know, it's good to be a Stooge."
