Not everyone: they got mentioned a lot in the What band or artist, can you appreciate but don’t like thread.
Of the big, well-known, mega-successful trios, The Police are probably my favorite. But there are a few more obscure three-piece bands I like better.
My all-time favorite trio is the 80s/90s Minnesota band Something Fierce, from where I went to college. They played catchy, clever power pop, and are, admittedly, super-obscure, although they’ve been enthusiastically praised by music journalist Steve Simels (in Stereo Review magazine and elsewhere), have had their Christmas novelty song “Satan Claus” played by Dr. Demento, and their music is currently available on sites like Spotify and Bandcamp.
