Beside taking their name from the British version of 'The Office,' this Reading, England, quartet is the ultimate party band. With sounds ranging from thumping, unapologetic dance grooves to epic rock anthems with pulverizing bass lines, their riveting synth-based tune 'We Are Rockstars' sums up this band live. Their shows are known to pack the energy of a Super Bowl, sometimes even result in injuries, stage dives and broken gear. Don't snooze on this one.
