Bertha Idaho (born c. 1895; date of death unknown)[1] was an American classic female blues singer.
Idaho's work might have remained obscure but for two factors: she was mentioned by John Fahey in the liner notes for his influential debut album, Blind Joe Death, and her recordings were reissued by Rosetta Reitz.
[7] The labels on the records state that three of the songs were composed by Delaney; Idaho is credited as the writer of "You've Got the Right Eye, but You're Peeping at the Wrong Keyhole".
Fahey's album Blind Joe Death was originally released by Takoma Records in 1959, in a pressing of fewer than one hundred copies.
[11] Reitz's music collections were built on old 78-rpm records of lesser-known performers, including Idaho, Valaida Snow, Georgia White, Bessie Brown, and Maggie Jones, and long-forgotten songs from better-known artists, such as Ida Cox, Ma Rainey, Bessie Smith and Mae West.
