Reducing rock as a genre to "straight white guys with guitars" gives me similar vibes to people who say all contemporary literature consists of middle aged guys talking about divorce and younger women.
While it's true that in the West white male artists (The Beatles, Rolling Stones, Led Zeppelin, Pink Floyd etc.) were the ones most heavily promoted, archived and mythologized from the 60's to the 90's; were the ones labeled as "classic rock" (ugh, I hate this term) by white critics, journalists, radio and record labels, people still confuse who was amplified with whom the genre belongs to.
In fact, rock wouldn't exist without black artists and musical traditions: blues (Robert Johnson, Muddy Waters, Bo Diddley), R&B (Chuck Berry, Little Richard), gospel (Sister Rosetta Tharpe) and jazz influences.
Artists like Fats Domino weren't the exceptions, they were the architects.
60's-70's when rock becomes "serious"?
Jimi Hendrix. Arguably, the most influential guitarist ever.
But also Santana, Sly & the Family Stone, Phil Lynott (Thin Lizzy, massively influential), Parliament-Funkadelic, Arthur Lee (Love), War.
70's-80's with punk and hardcore?
Death (proto-punk before the Ramones), Bad Brains, Poly Styrene (X-Ray Spex), Fishbone, ESG, Bush Tetras.
Rage Against the Machine, TV on the Radio, Kele Okereke (Bloc Party), Karen O (Yeah Yeah Yeahs), Chino Moreno (Deftones), The Mars Volta, Carlos Dengler (Interpol).
Mitski, Tosin Abasi & Javier Reyes (Animals As Leaders), Toro y Moi, Khruangbin, Big Joanie, Bartees Strange, Meet Me @ The Altar, The Linda Lindas, Yves Tumor.
A lot of these artists are rebranded as "indie" or "alternative" instead of "rock," but come on.
What about metal and heavy?
Living Colour, Sevendust, Body Count, Alien Weaponry (Māori metal), Bloodywood, Chthonic (Taiwanese), Tengger Cavalry.
Joan Jett & The Runaways, Pat Benatar, Deborah Dyer, Tracy Chapman, Patti Smith, Janis Joplin, Dolores O‘Riordan, Sinead O‘Connor, Heart, Melissa Etheridge, kd lang, Stevie Nicks, Bikini Kill, PJ Harvey, St. Vincent, HAIM, Big Thief, the Riot grrrl movement.
Queer or gender non-conforming rock?
Prince, Bowie, Freddie Mercury, Anohni, Japanese Breakfast, Perfume Genius.
Some non-Western rock scenes and bands?
Happy End, Yellow Magic Orchestra, RC Succession, X Japan, Boredoms, Luna Sea, Dir En Grey, Tricot, Boris, Mass of the Fermenting Dregs, Band-Maid, Polysics, Chatmonchy, Buck-Tick from Japan. Japanese bands export rock ideas, they don't imitate them.
Shin Jung-hyeon (godfather of Korean rock), Sanulrim, Jaurim, Hyukoh, Se So Neon, DongYang Gozupa, Huremic, Jambinai, Parannoul, Superstring, Tierpark. Korean rock was censored during dictatorships, which shaped its visibility.
