In 1969 Sanders released Karma, a highly accesible album that brought him widespread praise and commercial success. This was in no small part helped along by the presence of vocalist Leon Thomas, who certainly helped the recording find an audience with the hippie culture of the late 1960's who were accustomed to lyrical content in their music. Summun Bukmun Umyun (Deaf Dumb Blind) was not nearly as accessible to non-jazz fans - even many jazz fans must have been puzzled by it - and as such it is not nearly as well known.
