In this March, 2015 photo, a person sits at an upright piano that had been hauled up to Topanga Lookout in the Santa Monica Mountains in Calabasas, Calif. For a couple of days last week, a Southern California hilltop was alive with the sound of mystery. Hikers venturing to Topanga Lookout found a battered upright piano sitting on a graffiti-scrawled concrete slab with a panoramic view over the mountains between Calabasas and the Pacific Ocean. Turns out, the piano was used for a music video by Seattle-based artist Rachel Wong. The cinematographer, Michael Flotron, says he and four others used a dolly and rope to haul the 350-pound instrument a mile up the trail on Tuesday. After the shoot, it was too dark to get the piano back down. Flotron says people seem happy to leave it there. But if necessary, he'll haul the piano back down. (Photo by Michael Flotron/AP Photo)

In this Wednesday, January 7, 2015 photo, a Sri Lankan Catholic devotee Rita Anthony kisses her rosary as she prays inside her house in Colombo, Sri Lanka. The Vatican has said that it hopes that Sri Lanka's Christians can play a role in helping heal the wounds of the island nation's bloody 25-year civil war, when the Tamil Tiger rebels fought to create a separate homeland in the north for the minority Tamils, who are mostly Hindu. The war came to a bloody end in 2009, but many Tamils say they feel forgotten by the central government, which is dominated by the country's ethnic Sinhala majority, which is overwhelmingly Buddhist. Sri Lanka's Christians come from both the Tamil and the Sinhala communities, making them a natural bridge between the two sides. (Photo by Eranga Jayawardena/AP Photo)
