What does a b-sides and live-music disc release say about a group? Well if music history is worth anything, the answer would be that most frequently they appear late in a group's career after its popularity peaks. However, Matt Bellamy's ensemble is not much older than the millennium and has released but two albums. "Hullabaloo," says Muse - putting out a double CD.

The b-sides are not much different from the "a" ones - titanic efforts of complex musicality - melodies with shrieks, impressive by all standards. Some, though, are quite similar to the group's previous hits, and few disclose the whole scope of those works. "Yes, Please" is one of their biggest tracks so far on drums and tempo, while "Map of Your Head" - the next track on the disc - is Muse's purest ballad yet.

However the main attraction comes from "Forced In" - a trip-hoppy wordless whining in minor. Disc 2 show the group making their way live through "Le Zenith Paris," improvising in the solos and expanding the moans and beats of their classics - an event which Moscow has already witnessed twice, to great success.
