Swamp Dog Blues

Slide guitar or bottleneck guitar is a particular method or technique for playing the guitar. The term slide refers to the motion of the slide against the strings, while bottleneck refers to the original material of choice for such slides: the necks of glass bottles. Instead of altering the pitch of the strings in the normal manner (by pressing the string against frets), a slide is placed upon the string to vary its vibrating length, and pitch. This slide can then be moved along the string without lifting, creating continuous transitions in pitch. The technique of using a slide on a string has been traced to one-stringed African instruments similar to a “Diddley bow”. The tuning and bend filled playing style resembles the blues-harp.

The technique was made popular by African American blues artists. The first musician to be recorded using the style was Sylvester Weaver who recorded two solo pieces “Guitar Blues” and “Guitar Rag” in 1923. Some of the blues artists who most prominently used the slide include gospel singer Blind Willie Johnson, Blind Willie McTell, Mississippi Fred McDowell, Son House, Robert Johnson. Arguably the first influential classic electric blues slide guitarist is Elmore James, whose riff in the song “Dust My Broom” is copied from Robert Johnson and is held in particularly high regard. Blues legend Muddy Waters was also very influential, particularly in developing the electric Chicago blues slide guitar from the acoustic Mississippi Delta slide guitar. Texas blues musician Johnny Winter developed his distinctive style through years of touring with Waters.
