CSS are currently on the road touring their second album Donkey
CSS have admitted they are "happier than ever" after a tough year which has seen the band split with their bassist.
The Brazilian outfit are currently touring the UK with their second album Donkey.
Guitarist Ana Rezende said the Brazilian electro rock outfit are enjoying life on the road and the band are in a "good place" right now.
She added: "We're really happy playing this album live. It feels like more of a pleasure for us these days."
The Sao Paulo band broke into the UK singles chart with their biggest hit, Let's Make Love And Listen To Death From Above, last year and their song Music Is My Hot Hot Sex featured in a global iPod advert for Apple.
But the Brazilian outfit found themselves struggling financially and enduring a punishing tour schedule as they promoted their self-titled debut.
Ana said: "With all the mess that happened with the first album, it got really quite stressful for us.
The band is much tighter than we have ever have been and we feel much stronger now
"We were living in a suitcase for about three years and had no money and that kind of sh**."
They eventually parted ways with their bassist Ira Trevisan in April 2008 who put out an official statement saying she was concerned about "climate change" and wanted to "dedicate more time to fashion and other projects".
Since then drummer Adriano has taken up bass duties and ex-Cooper Temple Clause sticksman Jon Harper was drafted in.
"We came back together at the end of last year and restructured ourselves," Ana explained.
"Its better now and less chaotic. We have an amazing crew and all the stuff a band needs to relax and enjoy touring. We also live in London now so things are much easier for us.
"Adriano has slipped into his new role well and he is a really amazing bass player. Jon has also settled in too.
"Because of that the band is much tighter than we have ever have been and we feel much stronger now."
The band are due to appear at the Iceland Airwaves festival for the first time next week alongside Vampire Weekend, Biffy Clyro and Crystal Castles.
Ana said the glacial country is one place CSS have always aspired to visit.
"We never thought we would go there especially since we were born in a tropical country which is very hot. So going to Iceland is quite exotic for us and it sounds like a really great festival," she gushed.
"I heard about that hot swimming pool (Blue Lagoon) they've got there. I love that kind of stuff. I'll bring my bikini."
Singer Lovefoxxx recently collaborated with Primal Scream on their album Beautiful Future.
Ana said the band have no further plans to work with any other artists but she said she would love to team up with Mariah Carey.
"I'd love to work with her but I'm sure we would come up with nothing," she joked.

"We often aspire to collaborate with people we look up to and we like. But stuff like that has got to happen naturally."
CSS are due to release their new single Move next Monday.
Ana added: "We originally wanted the song to be called Hairflick because its about hair flicking but in the end we settled on Move. It's very summery."
