"I guess we're perfectionists in the way that when we make an album, we know it's going to last. It's important that it's exactly how we want it to be," Mars said. "But when the record is done, it's all about imperfection. It's all about playing live."
Ironing out things worked for the French-based band: "Bankrupt!" Phoenix's fifth album debuted at No. 4 on the Billboard 200 albums chart this month. "Wolfgang Amadeus Phoenix" peaked at No. 37.
Part of the anticipation behind the critical darlings in America can be attributed to the ubiquity of their song "1901," which appeared on their last album and was used in a Cadillac commercial. The platinum-selling track, a Top 5 jam on the rock and alternative songs charts, is the group's biggest hit in the U.S.
"Back when we did this Cadillac commercial, we were unknown here. The idea of doing something for such an iconic (car) was really funny to do," bassist Deck d'Arcy recalled (brothers Christian Mazzalai and Laurent Brancowitz round out the foursome).
Phoenix is on a world tour that wraps Nov. 22 in Dusseldorf, Germany. Mars said not having a hit before "1901" took off proved to be an advantage for the band on the road.
"We're lucky that we didn't have a hit single for a while, so when we play live, people are not expecting just one song and we don't tour as a greatest hits band, which can be sad I'm sure," said Mars, who is married to Sofia Coppola. "It's always the new album, and some from the last one, and less and less from the older ones."
D'Arcy feels the band attained gradual success over their 14-year career, but said they weren't prepared for the overwhelming reception they received in America.
"The U.S. was a surprise. ... We never expected the big bang," d'Arcy said. "The rest of the world we kind of experienced success on a smaller scale."
While both d'Arcy and Mars agree the band doesn't need to do another TV commercial to promote their music, they don't believe that commerciality devalues their sound. That may be a result of the way things work where they grew up.
"There's a weird law in France where they could use pretty much anything, any song on anything as long as it's less than 40 seconds so we grew up with this," Mars said. "We grew up discovering (Prince's) 'Little Red Corvette' on a weird Cheerios commercial, and I didn't mind it. I thought it was awkward, but I liked the song."
The members of Phoenix, who have been friends since attending school together, hail from Versailles, the posh section outside of Paris. Oddly enough, they're not very known in their homeland.
"We have a more underground success in France, which we feel keeps it cool. We are considered French, but not French because people don't think we are," d'Arcy said, smiling. "It's a funny one in France."
