LITHIUM HOMME has announced a collaboration with the rock band Alexandros, formerly known as Champagne, to create a rider's jacket. Using the pattern of their signature lambskin double rider jacket, both men's and women's models have been produced. They will be sold as official tour merchandise for Alexandros' five-city Zepp concert, which began on April 10th. Each jacket is priced at ¥24,000. Alexandros is a Japanese rock band formed in 2007. The four-piece band consists of vocalist and guitarist Yohei Kawakami, bassist and chorus member Hiroyuki Isobe, guitarist Maki Shirai, and drummer Satoshi Shomura. Until March, they performed under the name Champagne. Since last fall/winter, the band has collaborated with LITHIUM HOMME on collection theme songs and artist photos, and their album "Oblivion," featuring LITHIUM HOMME, is currently on sale.
