Bomber’s Row

In a maximum security prison in Colorado, three of the most dangerous terrorist bombers alive mix with a Cuban drug lord. From their cages in an exercise yard they converse, then a female barber with a secret cuts their hair. Based on true events and people, there’s a haunting, at times voyeuristic quality to looking in at these folk, and Paul Allman’s script mixes the echoes of a bombing survivor trapped under concrete with strange, dislocating uses of song and everyday chatter to good effect. On the downside, it’s hard to see what final point the piece makes. (Steve Cramer).
