Had a feeling it'd be up your alley
Definitely has an outsider vibe but unlike most outsider releases, Bobby seems fairly technically proficient despite the alien nature of his music. As some RYM reviews of the album point out, he appears to have a 6 octave vocal range and utilizes it to its fullest throughout the course of the album. And I guess he made/invented many of the instruments he plays (a la Moondog) on the album (apparently that's him posing with said instruments on the cover).
But yeah, definitely the most interesting and unique album I've discovered in awhile- gonna have to snatch it up and listen more intently. Seems like a great one to get stoned to)
