11 tracks, features 7 Beartrax Solo and 4 multi-track
all songs composed and arranged by Kai Kurosawa




Born in Japan, Kai Kurosawa picked up the electric bass guitar at the age of fifteen. Eventually he discovered the Warr Guitar (a leading figure of tap-style guitars), and not only self-taught himself but also self-created fresh new cutting edge musical techniques for this unique instrument. Today his primary axe is the Beartrax; a custom 24-string tap-style instrument which he co-designed. Widely considered as truly one of a kind player, he is frequently invited to teach seminars and clinics in the United States, Europe, and Asia. He is consistently busy working with various bands and creative projects; genres include jazz, progressive metal, rock, pop, and electronic music. To name a few collaborators, he has worked with musical masters such as Vinny Golia, Ponta Shuichi, Hiromi, Kiyomi Otaka, Thomas Lang, ISAO, Shane Gibson(korn), Charmaine Clamore, and Andrea Centazzo. Some of his works are out on popular TV shows such as NSIC, as well as on the big screen (theme song to Resident Evil recorded with gothic super star Collide). During off tour season, he works as a producer/programmer. He also brings online lessons on the bass and tapping instruments. Kai currently resides in Los Angeles.





“Kai stunned on the obscure Bear Trax: a hollow-bodied with two parallel fretboards, played simultaneously.  His “Turkish Rondo” solo was like a duel between guitar and bass masters.”

Asian American Jazz Festival

-- Kirk Silsbee, Downbeat Magazine



“… The guy is obviously a virtuoso, with a mind-boggling right/left brain command… When Kurosawa did get a solo feature -- on an unannounced heavy fusion piece -- he definitely got down, sounding like an amphetamine driven Alphonso Johnson underwater.”

-- Robert Bush, NBC San Diego



the MJF "What Is That Thing, And Does The Supportive Truss Come With It?" award goes to bassist Kai Kurosawa, playing an electric thing that had two necks, a gazillion strings and a design that screamed "mad scientist meets luthier.”

Monterey Jazz Festival

-- David Becker, AXS



“SHARP THREE can truly be called—not World Music—but Global Music. The same can be said of Kai Kurosawa and his writing.

Kai’s bass instrument of choice is the 24-string Beartrax “Big Mama Bear” that Kai himself designed. It is best described as a Chapman Stick on steroids.

The solo improvisational "explosion" at the end is all Kai. He is actually holding down the bass line at the same time.

“Lullaby for a Content” is from Kai’s pen and his skill with the 6-string bass proves that Kai is not a gear-head who relies on technology but rather on technique, not machinery but musicianship.

 “Kai Kurosawa stalking and soaring on tapped extra-stringed Warr guitar”

Angel City Jazz Festival

--  Greg Burk, MetalJazz.com



“… Kai Kurosawa on warr guitar / bass ... Again I was really amazed to hear a warr guitar played within a metallic based band. This, to me gives the music more dimensions. Kudos to Kai! Here’s hoping Kai as well as the others will contribute more than just live.”

“The trio is fired by the spirit of adventure, yet each musician knows that the take-off point is integral to the success of the journey. Their empathy is apparent throughout the recording.”

Andrea Centazzo : West Coast Trio (2008)

-- JERRY D'SOUZA, All About Jazz



“Kai Kurosawa was brought in to provide his tap guitar artistry via a couple of custom axes called a “bear trax” and a “ziggy.” This is already getting interesting.”

Daniel Rosenboom Quintet : Fire Keeper

-- S. VICTOR AARON, Something Else Reviews



“Kai Kurosawa's Warr Guitar Conterpoint is a well-crafted additive process piece featuring Kurosawa's own Warr Guitar… Interlocking Textures is an exciting album of electric guitar arrangements you won't hear anywhere else.”

Los Angeles Electric 8 : Interlocking Textures

-- Daniel Corral



“Kurosawa's deft playing of the Bear Trax provides a bass line appropriate to any number of funk style…”

-- Mike Oppenheim, All About Jazz


“the verses are calmer and show the versatile solo techniques within the group, especially Kai… The best thing about this album, however, is that it can be listened to repeatedly and you’ll still likely hear something new or identify an unknown voice you couldn’t place before.”


-- Lorelei Clarke, JazzReview.com



“… the relentless jabs of Kurosawa, setting up an explosive melodic unison… Ornette-ian challenge that Kurosawa splits apart with a solo that toggles between the sounds of 70s synthesizers and Jamaaladeen Tacuma underwater… Complex and exciting, Fire Keeper burns, lurches, and leaps with intelligent virtuosity and a breathtaking sense of ensemble cohesion. This might be where jazz is heading—so strap in and enjoy the ride.”

Daniel Rosenboom Quintet : Fire Keeper

-- Robert Bush, All About Jazz



 “Sharp Three is not an album that you will be able to discover in a few listens. The music is at times pretty complex and cerebral bit also, surprisingly, has raw live qualities that we don’t usually expect from this musical genre.

Sharp Three surely deserve that their music be heard by many. Highly recommended.”


-- Proggnosis.com



“Kai Kurosawa, who also plays the Warr Guitar, with an enormous fret board, the Warr guitar produces sounds unlike you’ve ever heard. It’s this blend of traditional and modern instrumentation that makes Kai’s work so fascinating.

Sharp Three is a treasure of diverse musical influences and unique orchestral arrangements that provide a deeply colorful sound experience. A must have for any music enthusiast.”


-- John Cola, drum.com



“Sharp Three put a wide mix of music together on their album, Zero Cool. Surpassing the quotidian jazz clichés about "moments" and "hipness," this album possesses sonority where even the stoniest non- emotes hear spirituality, Sharp Three provide music with enough cultural variation to lose self in parts or whole.

Kai Kurasawa on "probably all touch-style instruments in the known universe" is far beyond experimental, (the extreme 24-string Beartrax sound being one of the many).

Sharp Three are their own voices, with mastery of prior greatness and a 'now' liveliness that captures a calm, fresh sound.”


-- Fiona Ord-shrimpton, All About Jazz



“All the musicians are at the top of their field. The group as an ensemble provided even a feeling of comfort despite its completely technical music. Kai Kurosawa commanded the low end and technical unison riffs with his bass and Warr Guitar.”
