Paul McCartney Discovers New 'Great Band' With Goofy IG Filters

Paul McCartney is filtering out bad vibes in 2022, and ushering in wacky fun ... and he's doing it with the help of a new group he's discovered that may rival his old ensemble.

This Beatle is ringing in the new year by introducing the masses to a band he says he stumbled upon at his NYE bash ... which goes by the name of Linstrom. They're a heavy metal folk music act, consisting of 4 artists with very different faces ... and a boozy manager.

As you can probably tell -- they're all PMC, who seems to have discovered Instagram's many facial filters ... and is going to town with them.

Check it out ... Paul trots out his made-up band members, including Olga (apparently the frontwoman), an angelic anonymous keyboardist, Trinket the bass player, Mac the boorish boar-ish drummer and one final guy who says he handles the business end of things.

He's obviously having a grand old time with the goofy in-app feature ... almost like he's a freakin' kid again.

In real music news, Paul had himself quite a year ... and was eager to recap it on Friday. He put out an album, a couple books and was featured in a couple big documentaries -- plus other stuff, too.
