Bob Log III (born November 21, 1969) is an American slide guitar one-man band based in Tucson, Arizona, and Melbourne, Australia.

Log began his music career recording and touring with Mondo Guano, a four-piece slide guitar, blues, home-made percussion band based in Tucson, Arizona.

Upon leaving Mondo Guano, Log went on to perform as one half of the Delta blues rock duo, Doo Rag, with bandmate Thermos Malling.

After six years of making music with Doo Rag, Bob began a solo career, warming up audiences bands, including R. L. Burnside, Blues Explosion, Ween, Franz Ferdinand, and Ani Difranco.

These instruments, combined with his slide guitar work, telephone microphone vocals, and drum machine accompaniment, form the framework on which Bob Log constructs his songs.

His version of quick Delta blues is based on the sound that he and Thermos developed in the duo Doo Rag, with greater emphasis on guitar showmanship, fingerpicking, and one-man-band-style drumming with his feet.

"[3] An early press release from record label Fat Possum claimed Log had a monkey paw grafted on to his wrist after a boating accident as a child.

Log is quick to point out that all of these acts are carried out between consenting adults and individuals familiar with his brand of humor, stating, "First of all, if you come to my show knowing I've got a song called "Boob Scotch" and you get offended, I'm sorry but I've got to say just get out.
