There’s actually some overlap between blues and punk. For example, hill country blues, especially as practiced by artists like R.L. Burnside, has a wild, unpredictable energy, largely based upon raw performances that feel like classic punk rock. But it’s much harder for proficient instrumentalists to tap into that vibe, because once there’s a certain degree of musical skill, performances start to feel more prepared. But a band like Cream, at their best, brought punk to blues, and you can now add Albert Castiglia to that very short list of punk-blues virtuosos, with Wild and Free, a live show capturing the talented singer and guitarist at the height of his astoundingly rocking powers.
