1970s-style retro vintage artwork depicting a fierce musical battle between two distinct-looking robots wielding their instruments as weapons. One robot is sleek and futuristic, resembling a humanoid figure with metallic limbs and glowing circuitry, wielding a laser guitar that emits beams of light and sound waves. The other robot has a rugged and industrial appearance, adorned with gears, pistons, and mechanical parts, brandishing a massive drum set equipped with pneumatic drumsticks that strike with thunderous force. --s 750
