I had the opportunity to see them perform live in March in the Detroit area and they are astoundingly good even outside a studio. Their live performance carries so much more power and weight; the only thing I feel is lost are some of the finer points of Matt's vocals.
Fellow CBers posting their favorite Muse songs is what originally introduced me to them and I recently stumbled upon another band that I wanted to share with the community who take quite a few cues from Muse.

They have a very similar sound, if I am not mistaken that is their goal, which makes them a fairly enjoyable listen.
