Evanescence drummer Will Hunt says that the sessions for the follow-up to 2006's The Open Door are progressing well and that frontwoman Amy Lee is taking some "really big risks".The band are working with U2 producer Steve Lillywhite on the as-yet-untitled album which is due for release later this year and Hunt says that they have been experimenting with incorporating new, electronic elements into their sound."There are new colours in the pattern," he said. "There's a lot of cool new things going on, both electronically and futuristically. I think she's doing something that's very special and hasn't been done before. I'm a supporter. I think it's killer!"But Evanescence fans shouldn't worry about the band taking a new direction because it still sounds like them."It's always going to sound like Evanescence, 'cause it's Amy Lee singing," he explained. "But the vehicle for that voice can be different and still be Evanescence. She is taking some real big risks and honestly, I think it's amazing!"
