text: meaning of barriers?   barriers is a set of purer-than-pure berlin school electronica. the nightcrawlers -- peter gulch, tom gulch, and david lunt -- were known for this style of e-music. unfortunately, their fan base can best be described as a cult following. despite their purity and excellence, this trio never achieved anything close to the recognition that they deserved. all of their albums and cassettes are long out of print and only a small portion of their prodigious output has been remastered for cd reissue. this rare slice of history is essential electronica. it is worth every effort to track it down. ~ jim brenholts, all music guide
