In 2004, Haino released a pair of albums, both called Black Blues and both containing the same six songs — all blues covers (translated into Japanese), climaxing with two versions of Blind Lemon Jefferson’s “See That My Grave Is Kept Clean.” This acoustic version is, surprisingly, about six minutes longer than the electric version, but a lot of that is long moments of meditative silence, particularly on the songs that pass the 10-minute mark. His acoustic guitar sounds slightly detuned, almost like an autoharp, and is treated with just a little bit of reverb, while his vocals are sometimes whispered into the microphone with incredible intimacy. This is one of the few Haino albums that really must be experienced on headphones.
