Two of the greatest legends in free jazz and psychedelic rock, Keiji Haino and Peter Brötzmann, join forces after a long while in this four-album noise-fest.  My understanding that the vinyl pressing on Black Editions, which includes a 3-inch CD, is long sold out, which is unfortunate, but a standard edition is available for $100, a bit high, but for these two, and for a four-LP set, it just might be worth the price.
