Aleksi Perälä (born 1976) is a Finnish electronic music composer and producer. He has made music since 1988, and performed it live since 1996, switching between hardware and software over the years.

Early life and education Perälä's first reported interest in sound was at the age of 3, by the echoes in the Helsinki Central railway Station. In 1983, he started taking piano lessons, until he discovered electronic music on Finnish radio during the Second Summer of Love phenomenon in 1988. He taped music from the radio, and experimented with his synthesiser to "fill the gaps" left by the lack of electronic music that could be heard just over the radio.

Whilst being an exchange student in Michigan, Perälä first heard of Aphex Twin (Richard D. James) in the Autumn of 1993, and then heard Aphex Twin's "Selected Ambient Works Volume II" the following year. Perälä also found out about Rephlex; Richard D. James's own record label. This initiated Perälä to move back to Finland, and send demo tapes to Rephlex. He was signed onto Rephlex in 1999, starting his career in music.

In 2008, he obtained a music technology degree from Salpaus College.

Musical career and release style Perälä has a prolific musical career with over 150 full-length album releases spanning various electronic music genres. He has often released his music on unconventional formats including:

Audio DVD ("Colundi Sequence Level 1 and 2") Surround sound DVD ("Colundi Sequence Level 17.5") USB card ("Colundi Sequence Level 4") Cassette ("Colundi Sequence Level 6 and 17.3") Minidisc ("Colundi Sequence Level 7 and 17.4") Vinyl postcard ("Colundi Sequence Level 17.1") Wire recording ("Colundi Sequence Level 8") A piece of land, attempted through crowdfunding ("Colundi Sequence Level 9")

In 1999, he signed with Rephlex Records and released his debut album Lactavent' under the name Ovuca. He was a regular braindance act alongside other Rephlex artists such as Aphex Twin, Bogdan Raczynski, Ed DMX and Luke Vibert, touring on the Warp Magic Bus and in the USA.

His collaboration with British braindance artist Cylob led to the release of Cylobotnia, published on Rephlex Records in 2003.

In 2011, Perälä founded AP Musik, a sublabel of Rephlex. It was during this period that he began incorporating colundi frequencies into his music, releasing it through this label. Colundi is a term referring to 128 sound frequencies discovered and curated by Rephlex co-founder Grant Wilson-Claridge. Bandcamp published an article entitled “Colundi” is Music Tuned to Frequencies That Heal the Body". The official website once claimed: “We fail to reliably express our precise thoughts and intentions using words. Consequently, you may fail to understand us. We apologise for the effects of such misunderstanding.”

Perälä's output has been a result of his experimentation with this unique system.

His music often features intricate melodic patterns and unconventional rhythmic structures, and is often released in album format organised into different series, each relating to a specific theme, usually inspired by nature. The artwork is often photography of Finnish nature, which he says has influenced his music.

In 2021, Perälä received a two-year grant from the Kone Foundation, leading to a substantial volume of full-length albums released on a frequent bi-weekly or weekly basis. The grant's research focuses on additive synthesis while exploring various elements of world music. His work primarily involves sampling objects from his surroundings and replacing the partials with colundi frequencies. The ratios of the sound partials are influenced by natural patterns and real-world instruments, drawing inspiration from constants and sequences found throughout nature—such as phi, pi, and the Fibonacci–Pingala sequence.

The artist's prolific output has led him to forgo conventional track titles in favour of using ISRC codes, a practical approach to managing the vast number of tracks he produces.

He has produced remixes for many artists, including Larry Heard.
