Barrett Martin (born April 14, 1967) is an American drummer, composer, producer, award-winning writer, and Zen artist.
 He was the drummer for the Seattle, Washington groups Skin Yard and Screaming Trees, as well as the supergroups Mad Season and Tuatara.
 A multi-instrumentalist and producer, he does recording session work in Seattle and Los Angeles and has played on, or produced, over 100 albums to date.
 In 2014, he was awarded the ASCAP Deems Taylor award for excellence in writing for his liner notes in the Mad Season Deluxe Reissue.
 He is primarily known for his powerful tribal drumming style, which includes the use of the tom toms as a rhythmic component that replaces the traditional hihat and ride cymbal.
 He credits the jazz drummers Art Blakey, Max Roach, and Elvin Jones for inspiring this approach to his drumming style, as well as the rock drummers John Bonham, Keith Moon, and Neil Peart.
 He has also stated that the heavyweight boxer Muhammad Ali inspired his drumming at a young age, saying, "Ali was so incredibly fast on his feet, and his hands were both light and heavy at the same time.
 Float like a butterfly, sting like bee, that's the way a great drummer should play – light and heavy, the way Ali boxed."
Bob Becker (born June 22, 1947) is an American percussionist and composer known primarily as a founding member of the Nexus percussion ensemble, as well as a performer in the Steve Reich and Musicians ensemble.
 He primarily performs as a keyboard percussionist, but is also skilled in tabla and concert snare drumming.
 As a composer, Becker employs a multicultural approach by mixing the style of western military drumming with North Indian Hindustani idioms, such as raga scale patterns and tabla drumming.
 This fusion of compositional practices is the main focus of works like "Lahara" and "Mudra".
 There are also traces of influence from the music of minimalists like Steve Reich, which can be attributed to Becker's experience with that composer's music.
