Alejandra Cárdenas Pacheco, also known as Ale Hop, is a Peruvian artist, researcher and experimental musician based in Berlin. Her body of work includes live shows, recordings, sound and video artworks, research on sound and technology, and original music for film, dance and theatre projects.

She began her career in the 2000s in Lima's experimental and underground scene. In 2012, after several years of participating in different pop and electronic bands, she started her solo project after performing alone for the first time at Boiler Room, during her residency at the Red Bull Music Academy in New York.

Her studious approach to the themes addressed in her albums and pieces is constantly informed by her background as a researcher. She completed a BA in Art History, her MA in Sound Studies, additional studies in History of Science and Technology, and is currently pursuing a PhD at the Berlin University of the Arts. 

She co-founded the Berlin-based festival Radical Sounds Latin America (of which she was co-curator from 2019 to 2021) and currently runs the publication Border-Listening/Escucha-Liminal and the publishing platform Contingent Sounds, which emphasise critical discourses and artistic research around listening. She has made, screened and exhibited works internationally at institutions and festivals such as the CTM Festival (2022), the Haus der Kulturen der Welt (2021) and the Museum of Arts and Design in New York (2021), among others.
