The Veronicas have said they feel lucky to have worked with some of their idols on their upcoming third album.
Sisters Jessica and Lisa Origliasso have had a break between releasing records in which they changed labels, but Jessica said they felt proud of what they had achieved for their third album, The Veronicas.
Talking about working with Daniel Johns from band Silverchair, she said: "H e had basically all but retired, and was in this massive rock band, and here he is writing songs with us. He's a huge pop fan.
"We'd met him a few times, and he'd always tell us he was a fan, and Lisa and I are massive Silverchair fans. It was put forward to us that he wanted to maybe work on some music, we jumped at it. We co-write with lots of people, but they're normally songwriters, but Daniel is an artist, so that experience was incredible."
Continuing that they had worked with Butch Vig on the album, too, she said: " We asked him. We had a long time to work on this album, so we were trying different things and where we wanted to sit, musically. He obviously produced Nirvana's Nevermind, so he has such amazing talent. It's so inspiring working with someone like that.
"We worked with Billy Corgan from Smashing Pumpkins, too, which again was amazing and inspiring and not what people would expect. We get to work with so many people no one would expect us to. Maybe it's the black hair and red lipstick.
"[With Billy] we put the request forward and he agreed to meet us and just said, 'I was fascinated by the request. I wanted to meet you because I just wondered what two Australian sisters who make pop music would want with me'. But it really worked out."
The Veronicas is released on March 16 and UK tour information is available at www.theveronicas.com.
