Big four theory

In multiple genres of rock music in the late-80s and early 90s, four huge bands tended to dominate the public perception of that genre. The bands were often fairly diverse within the genre, with one standing out as particularly edgy, one being more pop-friendly, one being more laid-back, and one being a wild card.

Thrash had Slayer, Metallica, Anthrax and Megadeth

Grunge had Alice in Chains, Soundgarden, Nirvana and Pearl Jam

Pick a genre and tell me what bands would be its "big four".

Sludge: High on Fire (Alice in Chains), Baroness (Soundgarden), Mastodon (Nirvana), and Red Fang (Pearl Jam)

Bonus points if you can do this for baroque music

beethoven
