Post-Rock Fusion: Chicago in the '90s

The place to be in the '90s for cutting-edge genre-bending music was Chicago. Post-rock bands like Tortoise were pushing the envelope of modern rock with '70s-inspired progressive grooves, while instrumental groups like Brokeback were fusing hip-hop beats with minimalist jazz using little more than a six-string Fender bass. Meanwhile, noise-rock acts like U.S. Maple combined punk with free jazz.
