YOB is a doom metal band from Eugene, Oregon, composed of Aaron Rieseberg, Travis Foster and Mike Scheidt.
YOB was founded by the vocalist/guitarist Mike Scheidt in 1996. The original YOB was Scheidt with bass guitarist Lowell Iles and drummer Greg Ocon. However, by 2001 when the band's first album, Elaborations of Carbon, was recorded, the members were Scheidt, bass guitarist Isamu Sato (previously with the death metal band Thrombus) and Gabe Morley, the former drummer of Lightweight. Sato also operates H.C. Minds and Morley plays with Fingertrap.
