In (roughly) a year’s time, Hallelujah the Hills will release a 52-song, four-album set — one original new song for each card in a deck.

The idea is bonkers. It’s like a sonic “Apocalypse Now” or “Infinite Jest” or “General Hospital,” ridiculous, glorious, and absolutely attainable for Hallelujah the Hills’s frontman and songwriter Ryan Walsh.

Walsh admits that “DECK” sounds a little like something an extremely baked musician pitches to bandmates in a tour van at 2 a.m. (only to be remembered ten years later with a, “Hey, man, whatever happened to our plan to…”).

“How about 20 years? Because that’s when I came up with the idea,” Walsh told the Herald with a laugh. “I became really enamored with things like the Magnetic Fields’ ‘69 Love Songs’ and Guided By Voices’ ‘Suitcase,’ which is like four discs of songs that no one had ever heard, and the touchstone that I always talk about, the ‘Anthology of American Folk Music.’”

“So the idea came easy,” Walsh added. “But then I guess it was 20 years of getting my confidence up.”

The latest single from the gleefully-ambitious project “Alone, In Love” is, well, ambitious. The track is seven minutes long and filled with sunshiny harmony vocals and dark storms of guitar and viola feedback (and it’s very, very good if you like catchy, noisy indie rock) — get a live listen to the single Dec. 15 at the band’s hometown Sinclair show in Cambridge.

So Walsh isn’t just churning out stuff he’s not committed to to fill a quota. He’s serious about every track, even if he’s open to sneaking a bunch of (extra) strange tunes in.

“My little gatekeepers inside of me were shot,” he said with another laugh. “I’ve written all these different types of songs that I wouldn’t have written if I only got ten or 11 to bring to the band… This is freeing in terms of what kind of stuff I’m going to write but there’s still a lot of editing and worrying.”

If you love Hallelujah the Hills’ 2019 LP “I’m You,” the “Diamonds” record is for you — it’s more-or-less a proper studio album with “Alone, In Love” serving as the five of diamonds. The “Hearts” LP will be acoustic-oriented. “Spades” will be full of experimental, sonic freak outs. “Clubs” features lo-fi, punk rock sprints.

Typically, artists slow down as they age. Cramming half a dozen albums into half a dozen years is for young bands. It’s delightful to see Hallelujah the Hills battling its age.

“We get to make the rules of our band,” Walsh said. “No one is making a living off it. It’s all for our enjoyment and our fans’ enjoyment. So I like to make decisions that don’t fit some stereotypical career arc. I don’t know how to explain it. I just felt like I could do it, I could do 52 songs, let’s go.”

“The thing is, you haven’t earned anybody’s trust when you’re young,” he added. “Now we’ve earned the right to do this big crazy thing.”

Hard agree. In fact, hopefully Hallelujah the Hills’ flood of songs inspires other bands who are two decades in to make an absurd amount of music in a short span. Who couldn’t use a 40-track Hold Steady project about Moses or 45 songs from St. Vincent in homage to the rpm speed of vinyl singles?
