Hadrien Féraud is a French bassist, born in Paris on August 16, 1984, whose fast and harmonically dense electric bass playing took him from the Paris scene into John McLaughlin's band, onto Chick Corea's recordings and, since 2023, into the quartet Sonicwonder led by Hiromi. Both his parents were musicians. Discogs describes his father, Gérard Féraud, as a French musician, songwriter and technician, and Gérard gave him his first guitar lessons when he was eight. He wanted to play drums at first. At twelve he was given Jaco Pastorius's The Birthday Concert and turned to electric bass. When John Kelman reviewed his first album for All About Jazz in 2007, he described him as completely self-taught and unable to read music.

He came up in the improvised-music scene of Paris and, according to Bass Magazine, landed an important gig there at eighteen. He credits the French bassist Dominique Di Piazza with teaching him chordal playing, and has named Matthew Garrison as an influence. In 2004 he began composing for a solo album while playing clubs and jam sessions in the city. In 2005 McLaughlin invited him to play on two tracks of Industrial Zen (Verve, 2006), and Discogs credits him on bass guitar on "For Jaco" and "Senor C.S." He toured North America with McLaughlin in 2007, and Kelman reported that McLaughlin was calling him a rising star and the new Jaco. He is credited on bass guitar on all eight tracks of McLaughlin's Floating Point (Abstract Logix, 2008), and in 2009 he toured Europe with McLaughlin and the 4th Dimension, with Gary Husband on keyboards and Mark Mondesir on drums.

His own first album, Hadrien Féraud, came out on Dreyfus Jazz in 2007. He recorded and mixed it with his father in April and May 2006 in a home studio. It has fourteen tracks, includes reworkings of "Giant Steps" and "Rhapsody in Blue," and brings in McLaughlin on a new version of his own "High Jacked," the bassist Linley Marthe on "Giant Steps," and Biréli Lagrène on guitar on "Rhapsody in Blue." The next year he arranged six of the nine tracks of Lagrène's Electric Side (Dreyfus Jazz, 2008), recorded in January 2008 at Studio Sextan in Malakoff, and played bass on it.

In April 2007 he recorded at Mad Hatter East in Clearwater, Florida, a trio session with Chick Corea on piano and keyboards and the drummer Richie Barshay. Discogs credits him on acoustic bass on it, and it was issued as the fifth disc of Corea's Five Trios, titled Brooklyn, Paris to Clearwater (Stretch, 2007). He was Corea's bassist again on The Vigil (2013), recorded with Marcus Gilmore on drums, Charles Altura on guitar and Tim Garland on reeds and flute, with Stanley Clarke and Ravi Coltrane as guests on one track. French Wikipedia adds tours of the United States and Europe with the Dean Brown Band in 2012 and 2013.

He is based in Los Angeles, as Hiromi's 2023 press materials note. In 2016, Bass Magazine reports, Hiromi called him to take over the bass chair for the rest of a world tour on the recommendation of the drummer Simon Phillips, replacing Anthony Jackson. He was the first player she recruited for Sonicwonder, and he suggested the drummer Gene Coye, who also lives in Los Angeles. The quartet, completed by the trumpeter Adam O'Farrill, recorded Sonicwonderland at Skywalker Sound in Nicasio, California, in May 2023 and released it on Telarc in October 2023, followed by Out There in April 2025. In between, he released his second solo album, Born in the 80's (2015), made Eclectik (Cristal Records, 2021) as a trio with the drummer André Ceccarelli and the guitarist Sylvain Luc, and recorded A Soul in Time (Guitar One Records, 2024) with the guitarist James Morgan and Gary Husband, a record whose songs were co-written by Morgan and Dean Brown. Apple Music lists a new single of his own, "I get so (Aggravated)", dated August 4, 2026.

He plays a five-string electric bass, fretted and fretless, and Bass Magazine describes his signature Mayones Jabba HF models in both versions; Ken Smith announced a signature Burner bass with him in 2009. Kelman called his debut the work of a flexible and technically dazzling player whose speed serves lyrical, well-built solos, with a percussive attack and a fusion sound that uses filtered bass and sequencer-like effects, and he compared some passages to vintage Weather Report. The comparison most often made is to Jaco Pastorius, and his own list of influences also names James Jamerson, Bernard Edwards, Christian McBride, Richard Bona, Jeff Berlin and Linley Marthe.

He grew up on rock, blues, funk, rhythm and blues and new wave as well as jazz, and the records he plays on sit in jazz-rock and fusion: Discogs files his debut under Jazz-Rock and Contemporary Jazz and Eclectik under Jazz-Rock and Fusion. Most of his work is on electric bass, but he plays acoustic bass on the Five Trios disc with Corea. English Wikipedia reports that Down Beat's critics poll named him Rising Star electric bassist in 2008 and that Bass Player readers voted him Most Exciting New Player in 2009.
