Yes at the Revs games the 2 fan groups there have one half of the game each on the megaphone, stood on some platform, spending the entire game getting those fans in The Fort to sing their heads off for 90 mins.What MLS has yet to figure out is the insipid "supporters groups" who spend the entire match BANGING ON GODDAMN DRUMS and singing SONGS WITH NO WORDS drive people AWAY. By people, I mean, you know, me.
To be fair the atmosphere at the Sacramento Republic matches (they play one league down) is really good. And it was very hard to get tickets pre-COVID.
No question the Seattle/Portland rivalry is the tops in the sport. The Timbers have some lumberjack who cuts a slice off a huge tree with a chainsaw right after someone scores and presents it to the player later. It's a pretty good schtick I think.
You can read about the tradition here (near the end of the article): https://www.timbers.com/providencepark/supporters/timber-joey
Nothing is spontaneous from the crowd. It is the same (however many) songs over and over again being led by the megaphone and backed up with the drums.
Very much the same formula Palace fans have latched onto.
