Cilantro pesto beet fettuccine with arugula and cream dressing

Diva Dompe and Amanda Brown pad barefoot around Dompe’s rickety house in the sun-soaked hills of Echo Park, preparing a “cheesy” vegan sauce of cashews, garlic, olive oil and lemon juice to mix with spiraled zucchini noodles. Once the concoction is topped with chopped walnuts and put in a dehydrator for 20 minutes, the women will cheekily refer to it as “baked macaroni and cheese.” It’s a popular dish among fans of their raw food and vegan catering company Crops and Rawbers.

Later, Dompe, 22, and Brown, 27, head to the studio in Brown’s Eagle Rock home, where they play in the psych-art-rock band Pocahaunted with Brown’s husband, Britt. The house is cluttered with hand-decorated cassette tapes that Amanda and Britt put out through a record label they run called Not Not Fun. In their spare time, Amanda is writing a vampire novel while Dompe studies biology and sings in the LA Ladies Choir. Both women also make “collage art.”

Their catering side project, as they call it, operates largely off the grid -- popping up at art openings, rock shows and warehouse parties. It’s part of a small but growing DIY foodie movement among those at the vanguard of L.A.’s underground art and music scene.

“People don’t realize that just as there are all these professional people going to train at Le Cordon Bleu, there is a whole generation of chefs who are punks, and they’re partying and they’re hedonists and they’re into food and sucking the nectar out of life,” Brown says.

Starting a counterculture catering company is similar to starting a rock band, says Alex Brown, 27, of the food-blogging and vegetarian-catering team Hot Knives. “When you’re getting into music, you want to be into the most obscure bands with the smallest-release records. With food, it’s the same thing,” he says.

“Explaining why somebody should be into a Momotaro tomato is not that different from an Amoeba employee telling you that you should listen to ‘Forever Changes’ by Love,” adds his partner in Hot Knives, Evan George, 26.

Alex also plays in an experimental drone band with Britt called Robedoor and works for a gourmet food importer. George covers healthcare for the Los Angeles Daily Journal and moonlights as a chef at the popular Echo Park vegetarian cafe Elf, which is run by members of the former indie rock band Viva K.

The caterer who sells raw vegan desserts to Elf is Stephen Hauptfuhr, 35, of Mooi, who in the late ‘80s was largely responsible for jump-starting L.A.’s rave scene through a weekly downtown acid-house dance party called Alice’s House. He also has put out more than half a dozen records, mostly electronica and dance music, under various names, including Mr. Kool-Aid.

Hauptfuhr’s catering career grew out of weekly dinner parties he used to throw at his loft in the Brewery on the industrial outskirts of downtown L.A. These days, the thin, soft-spoken and intensely private Hauptfuhr mostly caters small private dinners and sells prepared food to Whole Foods, Naturewell and Elf.

The fact that this trio of newcomers to the catering world (all started operations within the last two years) is vegetarian, vegan or raw is, according to those involved, attributable to the nature of today’s increasingly eco-conscious food landscape.

Still, none of the groups is militant about its dietary choices and all have a healthy sense of humor about how they are sometimes perceived.

“Just because Diva and I love to be in the sunshine and we love fresh food and we love to make music and walk around barefoot doesn’t mean we’re hippies,” Amanda says. “I just always want to take things to the next level. One day, maybe I’ll become a liquid-tarian and then a breath-arian, where all I’m eating is my breath.”

And if you’re a vegan and you want to take things to the next level, there aren’t many places for you to practice your craft, George says. “That’s why people are doing it underground.”

Hot Knives came to be four years ago as a regular recipe column in the now defunct alt-weekly L.A. Alternative Press. In 2006, George and Alex pulled it onto their own blog, Hot Knives, publishing recipes they were working on along with liberal servings of the two -- George tall and serious, Alex bespectacled and zany -- goofing off with food and craft beer on video.

They also post musical pairings for the food they make. For example, “Walkin’ With Jesus” by Spacemen 3 is suggested as a soundtrack for bean on bean noodle salad. Their catering gigs initially came about because fans of their blog approached them to do a wedding. And cooking for fans is still the Hot Knives ideal.

“People who are like, ‘Oh yeah, I’ve been up late at night at my computer and I’ve been hungry and I’ve totally wanted to hang out in that website, and now I can hire those guys to chill with me and drink beer and make me my wedding feast,’ ” says George, taking a break from pureeing guacamole mixed with fresh English peas in the kitchen of the house Alex shares with his girlfriend, Lake Sharp, who performs in an experimental dance troupe called Body City with George’s girlfriend, Meagan Yellott. Hot Knives once catered a six-course private party to raise funds to send the troupe to New York to go on tour with the L.A. band Glasser.

Examples of musicians-turned-food fanatics aren’t hard to find. Terri Wahl, who played in the L.A. punk band the Red Aunts in the ‘90s, is the owner of Eagle Rock’s Auntie Em’s Kitchen. Alex Kapranos, the singer for Franz Ferdinand, used to write a weekly food column for the Guardian called Soundbites (one of his best pieces was titled, “Let me eat cake! I’m a rock star!”); ex-Shins drummer Jesse Sandoval is starting up his own taco truck in Portland, Ore., called Nuevo Mexico.

Randy Randall, the guitarist of the L.A. punk band No Age, says that’s because bringing people together through food is much like going to a rock show. Randall is vegan and a fan of Crops and Rawbers, who once catered a No Age show at the Echo Park gallery Tiny Creatures. He says the healthful nature of the food these new caterers serve plays into the “forward-thinking, progressive” nature of L.A.’s DIY punk scene.

“The goal with food and music is to take positive action,” Randall says. “There’s enough harsh stuff out there, so why do something negative?”

Hauptfuhr agrees. “During the rave days, we’d go out in the desert and have carnival rides and there’d be 6,000 people dancing. It wasn’t very healthy, but people were really enjoying what we were doing,” he says, plating a vegan “snikerz” cake he is serving at a fundraiser for the Hollywood gallery LACE. “Now, I’m doing something that I get the same response for, but it’s actually really good for you.”
