Stephen Bruner (born October 19, 1984), better known by his stage name Thundercat, is an American multi-genre bass guitarist, producer and singer from Los Angeles, California. He has released three solo albums and is most noted for his work with producer Flying Lotus and crossover thrash band Suicidal Tendencies. Thundercat appeared on Kendrick Lamar's critically acclaimed 2015 album To Pimp a Butterfly. In 2016, Thundercat won a Grammy for Best Rap/Sung Collaboration for his work on the track "These Walls" from To Pimp a Butterfly.
Along with the involvements with previous artists, Thundercat draws inspiration from jazz musicians such as Miles Davis, Mary Lou Williams and Ron Carter. Through this, he is frequently able to renew elements from old soul, funk, and jazz albums. Known as "digging in the crates", this method is best used to bring the sound, feel and emotion he wants to convey in his music. An example of this can be heard on his EP released in 2015 titled The Beyond / Where the Giants Roam. The most popular track on this EP titled Them Changes, also shares this creative renewal element. Them Changes contains a drum sample from the 1977 track "Footsteps in the Dark" by the Isley Brothers. This shows how Thundercat is able to bring in old records to create fresh elements that make his music smooth and hypnotic.
In 2016, Bruner revealed to XXL that he is working on a new album with Flying Lotus as a main contributor. In May of that year, Bruner appeared live with Red Hot Chili Peppers to play additional bass on their song "Go Robot" at iHeartRadio's release party for the band's 2016 album The Getaway. In August 2016, Bruner appeared live with Kenny Loggins and Michael McDonald in Chicago.
In 2017, Thundercat appeared on "The Tonight Show Starring Jimmy Fallon" to promote his album Drunk with Michael McDonald and Kenny Loggins.
