BELFAST — A Plastic Rose, whose debut album is being released this month, already has the presence of a band that will feel at home on a stadium tour. The band members gained experience this year opening a few shows for Snow Patrol (three of their five members are from Northern Ireland), and at a recent small gig at Belfast’s Oh Yeah Music Centre, the crowd went wild for songs like “Oceans” and “Kids Don’t Behave Like This.” Also on the bill that evening were two other talented, yet wildly diverse bands: the spunky, quirky Wonder Villains and the melodic Pretty Child Backfire, both of which have devoted followings.

The showcase was just one of several gigs that happen across the city on an almost nightly basis. For a country with a population of just 1.7 million, the musical variety and energy is mind-boggling. “We have not had that many bands break out yet, but there are so many in the queue,” said Gary Lightbody, the lead singer of Snow Patrol and president of the Oh Yeah Music Centre. Northern Ireland, he said, “is the most exciting music scene in the world at the moment.”

Snow Patrol began the the last leg of its world tour in Australia and North and South America, and Two Door Cinema Club’s just-released second album “Beacon” entered the British charts at No. 2. The global success of Snow Patrol and Two Door Cinema Club has helped pave the way for the current buzz.

Bands like General Fiasco (on tour in Britain this month), And So I Watch You From Afar (ASIWYFA), Fighting With Wire (which released a new album last month) and Cashier Number 9 have gained growing support internationally.
