TORONTO (AP) — David Bowie’s longtime producer says the best way to work through grief is through music. Tony Visconti and his band, Holy Holy, played a Bowie tribute show for about 900 people in Toronto on Monday. It was part of a scheduled tour but sold out after Bowie’s death on Sunday. Among the albums Visconti produced were Bowie’s 1969 album “Space Oddity” and his last one, “Lazarus.” Visconti says Bowie’s songs are “some of the best music that’s ever been written.”
