According to the records the first Italian punk hardcore band ever to cross the Atlantic ocean to go touring the USA has been RAW POWER.
It was 1984 and that year a San Diego based label called BCT Tapes released their demo (untitled, aka Brown Studio Tape) and some of their live stuff in the Last White Christmas compilations (recorded in December 1983).
Almost 30 years later Reggio Emilia's RAW POWER are still around and have recently announced that they will be touring mid-west USA this coming April.
The tour kicks off on April the 26th in Detroit, MI to end on May the 4th in Minneapolis, MN
