No type of guitar probably exists which has not been expertly fingered — and, quite frequently, processed to the point of unrecognizability — by Henry Kaiser. Over the course of several decades, the open-minded Californian's substantial output has represented a significant departure from customary techniques, while still retaining the instrument's main traits. This evolution has been complemented by Kaiser's extensive experience with an array of sonic cultures from around the globe. The instruments he employs, such as the baritones permeating the entirety of The Lost Chord, are typically crafted by highly skilled luthiers, and invariably resplendent with uncommon quality.

Through prolonged exposure to the sonorous timbre of the baritone one becomes attuned to its reassuring presence, even when it is subjected to ruthless modifications. The resonance of a larger body than that of a standard guitar provides, for those accustomed to holding such beauties tight, the comforting vibrations of a virtual womb. You might want to stay there and relish a materiality that is simultaneously cushioned and replete with unconventional silhouettes and tones.

As always, Kaiser shows a comprehensive understanding of the reverberating properties and penetrating harmonics of an acoustic model, as evidenced by the two spoken episodes that introduce and conclude the program, and especially by the splendidly dissonant "An Old Flame". Additionally, his expertise in interconnecting digital delays and pitch transposing devices facilitates the reiteration and expansion of minuscule components, generating pliable counterpoints where one can bathe in pure bliss while also experiencing flashes of disorientation ("A Sleep In The Deep", "Mawsoni")

In the most ecstatic form, as exemplified by "Knee Deep In Ghosts", a fantasy of Richard Pinhas surrounded by gnomes impassioned by Terry Riley's Shri Camel may be glimpsed in transparency. That particular piece is in fact identified by hypnotic waves punctuated by tiny fragments and broken phrases cycling upon themselves, before the whole turns into a somewhat modulated anarchy. Despite the semi-ironic juxtaposition mentioned above, these elements belong exclusively to Kaiser's improvisational conception which, as it often happens, combines trance and unruliness without caring for anyone's judgment.

There is a great deal of substance in this set to be considered and evaluated without preconceptions; patience and focus will be rewarded. In this reviewer's memory, no Kaiser record has ever overstayed its welcome, and plenty of them find shelter in his house. The Lost Chord is an essential addition to the collection. But there's something else. Once the final ripples of an album like this have faded away, the urge to reach for your own stringed partner signals that the ultimate outcome has been achieved. The transition from passive listening to active practice symbolizes a sympathetic connection to what was offered to us, which in turn triggers a desire to further explore and learn.

Nothing is more important.
