Background. hide embarked on a solo career in 1993 due to the downtime in X Japan. Initially wanting to hire several different vocalists because he was unsure of his own voice, he eventually began taking vocal lessons from Toshi's coach and sang the material himself. Wanting to contrast something unusual with a pop background, hide hired Yukinojo Mori to pen the lyrics to his first two A-sides. As a kid, hide was fond of Bow Wow's 1982 album  Warning from Stardust, where the A-side songs had lyrics in English and the B-side in Japanese. Liking the Japanese lyrics better, hide only realized Mori was their author afterwards. "50% & 50%" was written after the A-side and B-side on "Eyes Love You" An acoustic rendition of the song, referred to as "50% & 50% (Crystal Lake Version)", appears on hide's first studio album "Hide Your Face". In a promotional video for "Doubt", hide is backed by his future Spread Beaver bandmate I.N.A. and Jennifer Finch and Demetra "Dee" Plakas of American all-girl grunge band L7 .
