In a 2008 Travelodge sleep study, 2,250 Britons voted Coldplay the most slumberrific band on the planet. The No. 3 act? Glasgow's Snow Patrol, which supports the heavy-lidded London pop stars on this leg of their held-over Viva La Vida tour. Perhaps to stave off the dangers of somnambulism, Howling Bells also opens. Tickets $49.50-$97.50.
