I'm so glad Lena get's to have the band to work with her. They make such a good sound.
I agree with Dradeel that I always wanted the girls to do something sorta industrial.
Some form of dark pop-rock with a backing orchestra sounds like a dream of mine.
They just need to write the music so it doesn't feel more energetic than Lena's singing. I think her voice is nice, but she needs to practice on how to make her falsetto notes sound more lively. I think most of us know how much of a pip-squeek voice she is when she sings together with Yulia. :| So I don't think dance-pop would suit her, unless she finds a singing technique that matches up with it.
