Blind Willie Dunn was a pseudonym that guitarist Eddie Lang usually used when he teamed up with Lonnie Johnson. Even the songwriter's credit on these records was listed as Johnson - Dunn instead of listing Lang's name.
It is said that the pseudonym came from a newspaper vendor that Lang was friends with, but some Jazz historians doubt that claim and suggest that the name was a commercial gesture, designed to cash in on the popularity of African-American Blues guitarists like Blind Lemon Jefferson and Blind Blake.
The Gin Bottle Four sessions are no milestone in the history of Jazz, but they did bring together some interesting mixed-race groups that spawned a few funky, feel-good tunes. It is also one King Oliver's better performances as a sideman, rather than as a band leader.
