Harley's ever-growing popularity with audiences outside of the Punk and Hardcore world, is a testament to the ORIGINS of alternative music and lost histories from the visionaries who created it. It has often been said, there would be no METALLICA, GREEN DAY or FOO FIGHTERS without the CRO-MAGS. In a world searching for authenticity- it doesn't get any more real than Harley. The CRO-MAGS are known as one of the most influential hardcore bands of all time.
