Sonic explorer Jon Porras crafts evocative soundscapes using guitars as well as both analog and digital synthesizers. He first came to prominence as one-half of Barn Owl, a beloved psychedelic drone duo from the Bay Area whose recordings ranged from the mystical doom metal of 2008's From Our Mouths a Perpetual Light to the sludgy electronics of 2013's V. As a solo artist, Porras released a few recordings of arid, desert-like drone under the name Elm near the end of the 2000s before going by his given name, starting with 2011's Undercurrent. While his initial solo releases were primarily focused on guitar, Porras switched to frozen electronics with 2014's Light Divide, followed later in the decade by warmer electronic works like 2018's Voices of the Air. 2022's Arroyo is a brief, minimalist set of glacial piano-based compositions.
