Swamp blues

[4] The sound of swamp blues was characterized by "eerie echo, shuffle beats, tremolo guitars, searing harmonica and sparse percussion".

[5] Swamp blues originated in the Black communities of Southwest Louisiana in the 1950s[2] and was particularly associated with record producer J. D. "Jay" Miller.

[6] The most successful and influential artist with whom he worked was guitarist and harmonica player Slim Harpo.

[7] Other major artists included Lightnin' Slim, Lazy Lester, Silas Hogan, Lonesome Sundown,[5] and piano player Katie Webster.

[6] A number of their songs, particularly those of Slim Harpo, were covered by British Invasion bands, including the Rolling Stones, The Kinks and the Yardbirds.
