The metalprog Dream Theater will release through Rhino Records a double CD with the best of the group, which will ironically be called 'Greatest Hit & 19 Other Pretty Cool Songs' (A big hit and 19 other good songs).
Work is expected on March 18, although further details have not yet been revealed. Recall that the band released their new album called 'Systematic Chaos' in 2007, well received by the public although perhaps something more musically novel was expected.
The first single was the song "Constant Motion", of which we see the video here:
