Peach Tree Rascals play the Paramount in Boyle Heights, Friday, Nov. 20

The San Jose collective behind 'Mariposa' brings its West Coast run to a historic second-floor ballroom on the Eastside.

Walk up the stairs at the Paramount on a Friday night and you're in a ballroom that has seen Chicano rock bands in the '60s and punk shows in the '80s. On Nov. 20 it gets a group that blew up on the internet with a breezy, bilingual-feeling summer song and has been turning that moment into a touring career ever since.

Peach Tree Rascals play The Paramount in Boyle Heights on Friday, Nov. 20, at 8 p.m. Tickets are on sale through AXS. The room holds 400, which is small for a band with a song that has been streamed as widely as theirs, and this is the first Eastside show we have on record for them.

The Los Angeles date sits in the middle of a West Coast swing. The band already played San Francisco on Nov. 7 and Santa Cruz on Nov. 8, and after Boyle Heights they head to San Diego on Nov. 21 and Orange County on Nov. 22. If you have friends in either of those places, this is the one tour weekend when everybody can catch them on back-to-back nights.

Peach Tree Rascals are a music collective formed in San Jose in 2018, working across indie pop, hip-hop and R&B. The song that put them on the map is "Mariposa," and the band has said as much themselves: in a Ticketmaster interview marking five years of the track, they called it the song that "put us on the map." Chicago's WBEZ talked with them about its viral run, too. More recently they have kept releasing singles, including "Song From Hell," which Dork described as a sunny indie-pop bop.

The venue matters here. The Paramount is a historic second-floor ballroom at 2708 E. Cesar E. Chavez Ave., in a 1920s building that the LA Conservancy describes in Renaissance Revival style. It has hosted everything from Chicano rock groups in the '60s to punk bands in the '80s, according to The LA Local's history of the room. After sitting empty for a year and a half, it reopened to live music, as KCRW reported, and its stage and bar were redesigned to honor the building's past.

A band built on a viral summer song, in a ballroom that has hosted Eastside music for a century.

That pairing makes sense. Peach Tree Rascals are a Bay Area crew whose sound pulls from several genres at once, and the Paramount is a room whose whole history is about the Eastside making space for music that didn't fit neatly anywhere else. A 400-capacity ballroom also means you'll actually be close enough to see the band trade parts, which is half the fun of a collective like this one.

What to know before going: it's a Friday with an 8 p.m. start. The Paramount is on Cesar Chavez in the heart of Boyle Heights, so plan your parking or Metro ride ahead, and leave time to climb the stairs before the set.

Tickets are live now. With a 400-cap room and a song this many people know, don't sleep on it until the week of.
