Career
He was the last to join the band in replacement of their former bassist "Key" who departed the band in 1999. Uehara"s playing style is highly influenced by Flea, the bassist for the band Red Hot Chili Peppers. Uehara is characterized by his twangy and heavy slapping and popping bass style, which is unique in nu metal, as it is more of a funky bass playing style.
In many of the band"s songs his playing is easily audible over the harsh vocals and guitar riffs.
He plays Sadowsky jazz basses and a Modulus FB4 and also sports tattoos that resemble those of his idol, Flea. He very rarely sings, but in some songs such as "Houchou Hasami Cutter Knife Dosu Kiri", "Kyoukatsu" and "Nigire Tsutsu", he has provided backup vocals.
