Crazy Mountain Billies is the alias used by American multi-instrumental musician A.P. Bormes to describe the full band sound created by the solo performer. The music is created by taking hand percussion and electric bass- and pre-recording tracks which are then performed over with vocals and a wide range of acoustic instruments (most notably banjo and guitar). The sound is a deviated form of bluegrass which has been described as Hardgrass and has become a genre entirely of its own. One of the the very first tracks was recorded with a loop pedal and an 8-track outdoors in the woods of Black Hills, South Dakota before A.P. Bormes moved to Hollywood, CA to study Audio Engineering and begin recording the first two albums.

After two years in the city it was time to get back out in the mountains so A.P. Bormes moved to Montana and completed the records as a double release in 2009 and named the band after the Crazy Mountain range which inspired much of the work. Shortly thereafter ''Badlands II" was recorded and released in February 2010. Then A.P. Bormes moved back to South Dakota to record ''Badlands III'' inside a log cabin (naming the series after the rugged badlands country of the midwestern prairies) and released the record in April 2011. C.M.B. spent the remainder of the year touring the U.S. before going back into the log cabin studio to record the album ''Hit Like A Hammer" which was released March 31, 2012- while C.M.B. is back in the studio recording a new E.P.

All of the C.M.B. material is self-recorded, produced, written, performed, mixed and mastered. The instruments used include: 5 and 6 string banjo, 5 string bass, acoustic guitar, mandolin, slide guitar, classical guitar, autoharp, jaw-harp, harmonica, tin whistle, washboard, vibraslap, shakers, cabassa, tambourine etc...
