Public Image Ltd was a highly stylised percussion based band that was both experimental and challenging. Aided by a prominent bass sound from the wonderfully named Jah Wobble, the music was the perfect fit for front-man John Lydon's unusual voice. It's the musical equivalent of an art student with a paintbrush and clinical ADHD. It's not passive listening, you have to engage with it to appreciate it. The first album, First Issue, is considered a classic by many folks, and looking back now it's clear that PiL was years ahead of its time.
