Before the new metro in Lausanne was finished in 2008, Patricia Bosshard asked the reponsible people at TL (Public Transport Lausanne) to compose the metro station jingles. Together with sound engineer David Scrufari they recorded local sounds and sound environments and produced the short pieces. The station announcements were spoken by Renato Häusler, who shouts the hours from the cathedral tower in four directions since 2002 (a tradition that goes back to 1405, originally to alarm the people of fire, nowadays announcing the hours between 22h-2h).
