Calling themselves “Generation Terrorists,” the Preachers set out to bring political revolution back to rock ‘n’ roll.

Dissatisfied with the happy-go-lucky pop acts that dominated the British charts in the ‘90s, the band sought to make the public aware of social welfare issues, while revitalizing the punk and rock scenes.

Sometimes, the Preachers got more attention for the bizarre antics and still-unexplained 1995 disappearance of guitarist Richey James than for their music. But the band stayed vital when many of their contemporaries fell from favor.

This February, the Preachers gave a rare concert in communist Cuba for a couple thousand fans including president Fidel Castro. The boisterous and anti-American show put the band back in the spotlight.

The Cuban excursion is the focus of the group’s upcoming DVD, “Louder Than War.” The disc features the live set from the Karl Marx Theatre in Havana and includes bonus audio tracks, an exclusive interview with the band, and a chronological record of the entire trip.
