Of all the acts set to appear at tomorrowโ€™s Madness on Main music festival, probably no one is chomping harder at the bit to get onstage than the Linus Pauling Quartet. For more than 20 years, the cerebral stoner/psychedelic/monkey rock quintet (yes, quintetโ€ฆdonโ€™t ask) has been a fixture of the Houston music sceneโ€™s darkest, weirdest corners, blasting out thoughtful tunes about Victorian literature, Prussian physicists and mind-blowing bong rips in roughly equal measure. But life has conspired to keep them out of the spotlight for nearly six lunar cycles now, and on Saturday, theyโ€™re planning to release all the pent-up distortion in their souls in a single, mighty, electrified orgasm.

โ€œLarry [Liska], our drummer, had a lot of stuff at his day job that was preventing us from playing together live much,โ€ explains LP4 guitarist and co-founder Ramon Medina. โ€œFrom May to November of last year, we didnโ€™t play any live shows. Lately, weโ€™ve been playing a lot of record stores. This weekend is the first time in a while weโ€™re coming out with the big guns.

โ€œWe just want to crank up the amps, make ears bleed and just rip shit up, because we havenโ€™t had a chance to do that in a while,โ€ Medina continues. โ€œSo, we really just want to be loud and stupid. It should look like the apes in 2001: A Space Odyssey, when theyโ€™re just beating each other with sticks.โ€

Thatโ€™s certainly the spirit in which the groupโ€™s latest album, Ampalanche, was named. The wonderfully fantastical press release accompanying the recordโ€™s launch last year relates the tale of a mystical journey to discover the ancient Tube Lords hidden deep within the mountains of Kashmir. Predictably, that expedition ended in disaster, to be rendered in the title trackโ€™s stop-motion animated music video slated for release in the coming months.

The album isnโ€™t all heavy guitar rumbling, however; far from it. Other highlights include โ€œSlave to the Die,โ€ a gently folky number featuring flute from Mlee Marie (Hearts of Animals), and โ€œPlanck,โ€ a pop-tinged tribute to the founder of quantum theory with lyrics by Brandon R. Brown, professor of physics and astronomy at the University of San Francisco.

โ€œThis is kind of a more varied record, so we have lighter songs and more rockinโ€™ songs, as opposed to a straight-out, punch-you-in-the-face-for-30-minutes kind of thing,โ€ Medina says. โ€œThe pattern seems to be, we have one balls-to-the-wall rock record, and then the very next one ends up being something where we just jam or just write more all-over-the-map things. Iโ€™m sure the next one will be just the opposite โ€” just straight ridiculousness.โ€

Unless, of course, it isnโ€™t, the guitarist adds.

โ€œWe donโ€™t really plan anything,โ€ Medina says. โ€œWe just throw stuff together, and what comes out, comes out.โ€

Ampalanche was written and recorded during the bandโ€™s unintended retreat from the stage in 2015 and recorded at bassist Steve Finleyโ€™s Digital Warehouse studio. The vinyl was released by Vincebus Eruptum, an Italian label with a keen interest in weird American rock.

โ€œItโ€™s funny โ€” people in Europe like what weโ€™re doing, and over here, no one could care less,โ€ Medina says, laughing. โ€œThatโ€™s pretty much the case, but I understand why that is. Weโ€™ve been around for so long, everyone here is like, โ€˜Ehh, I saw โ€™em last time, when they were babies.โ€™

The recently released digital version of the album, however, has an extra treat for the Quartetโ€™s most severely stoned fans: a nearly hour-length jam titled โ€œVi, de Druknede (We, the Drowned)โ€ that features some very strange instrumentation and sounds like the background music one might hear in a seedy Turkish drug den.

โ€œI donโ€™t know why, but I always get instruments that are completely useless,โ€ Medina says. โ€œInstead of buying something practical, itโ€™s always something stupid like an electric sitar. I had a didgeridoo, and I had a singing bowl. We just put two electric tablas rolling, and we had the Grendel doing some weird oscillations. It was one take live, pretty much, and it was really fun!

โ€œThatโ€™s the nice thing about getting to do the digital bonus track โ€” if someone wants to sit down and listen to us wank around for like an hour, they have the option to do that,โ€ he continues. โ€œItโ€™s nice background noise to kind of chill to.โ€

Chilling is all well and good, especially with a cool buzz going. Just donโ€™t expect to bliss out with the Linus Pauling Quartet at Madness on Main. Tomorrow, theyโ€™ll be striving to make the Ampalanche as large, loud and dangerous as possible.

โ€œWeโ€™re going to do a mix of more heavy songs, because weโ€™ll have the big amps, finally,โ€ Medina says. โ€œAs much as I love my little Fender combo amp โ€” itโ€™s got some great sounds on it โ€” when I plug into my Marshall with the four 12s, full-blast, itโ€™s just a gorgeous sound. That wave of sound in your chest is just gorgeous. Weโ€™ll be going for big, dumb, fun rock.โ€

Good to know. If youโ€™d like to enjoy the performance properly, it might be prudent to bring a windproof lighter.

Linus Pauling Quartet will appear at the Madness on Main festival at 8 p.m. Saturday at the Continental Club, 3700 Main. Admission is $25 at the door.ย
