Axel Zwingenberger is a world-renowned boogie-woogie pianist. He was born in Hamburg, Germany, in 1955, and after eleven years of conventional piano tutelage, became enamored with American jazz, blues, and boogie-woogie when he first heard it in 1973. Steam locomotives comprise his greatest passion beyond music, and the German reunification in 1990 provided access to the east's remaining steam operations. He photographed them with gusto, and even held benefit concerts to help keep them running. In 2000, he published Vom Zauber der Züge (The Magic of Trains), a 372-page book of his photography.
