Three versions of the Disco Biscuits will be in Boston over the holiday week — Same guys, same adventurous spirit, but three wildly different shows in as many venues.

The party begins Monday at the Sinclair, moves up to Royale the next night, and then goes big time with a New Year’s Eve show at Roadrunner. Expect a few variations on the Philadelphia band’s trademark mix of techno beats and organic jamming.

“Over three nights it progresses musically, and also in the size of the club,” says keyboardist/singer Aron Magner. “It almost seems like the metamorphosis of a band over the course of a career —you start in a smaller club, and work your way to a big, well-respected one. I love it when we do things like this.” Though the band hasn’t played New Years in Boston before, they did a memorable one in Worcester for 2000-01. “I remember a crazy snowstorm, and that was the state of the entertainment industry before COVID: the show must go on.”

For the first night at the Sinclair, the Disco Biscuits will appear as their seldom-seen alter-ego band, Tractorbeam. Without vocals or formal songs, it puts their electronic side upfront. “Every Tractorbeam performance pushes the boundaries of what the band thought was possible, because we take even more risks. We treat it more like a club DJ show, in that it flows fluidly through the evening, with different sonic spectrums, it has an arc and hopefully a denouement. Our bassist Marc (Brownstein) will have a bass synthesizer, our guitarist Jon (Gutwillig) will have synth pedals, Marlon (Lewis) will have drum pads and I’ll have my space station of keyboard wizardry. We think of this as ‘If the four of us were one DJ, what would that sound like’?”

The New Years show at Roadrunner is billed as the “Boston Techno Party,” and a few surprises are in store. “Our New Years shows are always a release – We’ve had shows where we pretended to be different versions of ourselves, wrote songs and did crazy things. We try to incorporate elements of the city where we’re doing it. You want a spoiler alert? There will be things falling from the sky at midnight.”

The Disco Biscuits have always thrived on outlandish concepts. Their last studio album “Revolution in Motion” was a space/sci-fi rock opera, and not even the first one they’d done. “When that idea was hatched I was the first to say ‘Yeah, I love it’ — and not even because I was sold yet, but it was such a good thing to write to. It needed 16 songs to tell the story, and we couldn’t have written them otherwise. That’s one way of doing it — but we still do the other way, which is ‘Hey, I just wrote this random unconnected song’.”

The band had a bit of a shakeup this year with Lewis (their third drummer) joining in October; the other three have been together for three decades. “We’re playing songs that we’ve never done with Marlon, so we’re coming in with the same curiosity that the fans are. There are so many moments where I turn around and smile, not just at Marlon but at what we just created. Those are the moments I live for.”
