Fortunately for Tokyo's large number of aspiring jazz musicians, Italian guitarist Gianni Guido is making a habit out of performing with amateur players.

Guido, a guitarist comfortable playing bebop, swing, free jazz or funk, will play a jam session with amateurs at the Four & More jazz club near the Asakusa area of Tokyo on April 6. On the same night, Guido will also perform with the Kunio Kato Piano Trio, accompanied by a vocalist.

Tokyo-based Guido, born in Naples in 1969, regularly jams with amateur players a generation older than himself at jazz clubs in Tokyo, emblematic of the fact that the baby-boomer generation in Japan is approaching retirement and has started to once again take up the musical passions of its youth.

The concert will include instrumental jazz standards made famous by Miles Davis and Bill Evans, such as Frank Churchill's "Some Day My Prince will Come" and Richard Rogers' "My Romance," and vocal standards such as "I Can't Give You Anything But Love." Guido, who was a permanent member of The Jazz Crusaders (with whom he played the Montreux Jazz Festival) in the 1990s, and has variously based himself in London, Los Angeles and Paris during his career, will also perform his own originals on the night.

The concert starts at 7:45 p.m. and takes place at Four & More, Espoir Iriya B1F 2-25-4 Senzoku, Taito-ku (tel. [03] 3876-5567). The venue is near Iriya Station on the Hibiya Subway Line.
