Razteria (Renée Asteria Peñaloza, she/her) is a San Francisco Bay Area singer-songwriter and band whose multilingual music moves freely between Latin grooves, reggae, rock, pop, alternative R&B and global influences. Asteria leads the project in close collaboration with guitarist-producer Dave Shul. Together they combine expressive vocals, rhythmic depth, emotionally driven songwriting and modern production with a throwback sensibility. Her sound has drawn comparisons ranging from early No Doubt and Sade to Bomba Estéreo, H.E.R., Nathy Peluso and Kali Uchis.

With roots in Bolivia, the Netherlands and the United States, Asteria released her self-titled debut in 2005. Since then, Renée has released Caras de Agente Doble E / Faces of Agent Double E (2007), RazteRia (2010), Maz Raz (2013), Aventurera (2016), the Cruzando Corazones EP (2017), Infinity (2018), Pure Love (2020, as Renay), Space to Play (2021), Tocar las Estrellas (2023) and Prowess Blossoming (2024). Aventurera includes its title track and "Once Again," which won the Grand Prize in the World Music category of the 2016 John Lennon Songwriting Contest. With Shul, she made the alternative Latin album Tocar las Estrellas, which was added to the San Francisco Public Library's Bay Beats collection, and the retro-rock album Prowess Blossoming.

After a creative hibernation in 2025, Razteria returned in 2026 with two singles a month: 10 releases from "Reflection of You" (Jan 16) and "Oscuro y Claro" (Jan 30) through "Gravity Free" (May 8) and "Blink of an Eye" (Sep 25). Renée wrote and produced the music with Shul, and the two recorded it together. The singles feature drummer Ronnie Smith, keyboardist Bob Crawford, drummer Alcide Marshall on "Oscuro y Claro", bassist Waddell Bell and keyboardist Raliegh Neal on "Surrender", Daniel Makovej on rabab on "Sing It All Out", drummer Jay Lane on "Breathe One More Breath", and horns by Daniel Casares (sax and horn arrangements) and Joel Behrman (trumpet and trombone). Mixing is by Willie Samuels (Studio Trilogy) and mastering by Justin Weis (Trakworx); full credits at asteriarecords.com. The singles lead into two full-length albums: the R&B-focused Reflections and a rock-leaning album.

Live, Razteria is a dynamic 6-piece band of veteran musicians that plays originals and covers across genres. Highlights include Brick & Mortar Music Hall, Golden Gate Bandshell, Ashkenaz, Mill Valley Fall Arts Festival, Sonoma County Fair, Laurel Street Fair World Music Festival, WorldFest Los Angeles, Northwest World Reggae Festival, Reggae on the River and Montreal Jazz Festival (full list). "Baila" was an ISC semi-finalist (2019), "Inspire Me" was an ISC finalist (2020), and the "Life Is Too Short" music video was an official selection at Another Hole in the Head (SF IndieFest, 2024).
