Mabe Fratti, a Spark in Mexico City’s Experimental Music Scene

Ten years ago, the cellist and experimental composer Mabe Fratti came across a strange painting by Paul Klee. “Angelus Novus” depicts an angel, wings splayed, eyes wide open, who looks as though he is about to flutter away from whatever he is looking at. “It’s a metaphor for history,” she said, video calling from her friend’s living room couch in Berlin. “The philosopher Walter Benjamin wrote about it: this idea that we’re looking forwards, but also always looking back.”

The concept would go on to form the basis for “Angel Nuevo,” the first song Fratti wrote on her new album, “Sentir Que No Sabes,” out Friday. “I wanted to talk about what it feels like to know you want to progress, but not know where you want to go,” she said of the track, which starts out quietly and builds in an anxious crescendo.

Moving forward hasn’t exactly been a problem for Fratti, 32, who was born in Guatemala and is based in Mexico City. Since releasing her debut album, “Pies Sobre la Tierra,” in 2019, she has put out two more solo records, in addition to collaborations with her partner and producer, the Venezuelan musician Hector Tosta (known as I la Católica); the German electronic artist Gudrun Gut; and her improvisational quartet Amor Muere. In just five years, she has built a reputation as the most prominent member of Mexico City’s dynamic and rapidly evolving experimental music scene.

Driven by an influx of musicians to the metropolis and the establishment there of new institutions — sound galleries like 316 Centro in the city’s La Merced neighborhood, and labels such as Umor Rex — the Mexican capital’s avant-garde music community has flourished in recent years.

Older musicians have been sowing these seeds since at least the 1970s, Fratti said, citing Ana Ruiz, a pianist who helped create Atrás del Cosmos, a “community of improvisers Don Cherry participated in,” and the saxophone player Germán Bringas, who founded the venue Jazzorca in the 1990s.
