input: Unlike the Cubists, Mondrian still attempted to reconcile his painting with his spiritual pursuits, and in 1913 he began to fuse his art and his theosophical studies into a theory that signaled his final break from representational painting. While Mondrian was visiting the Netherlands in 1914, World War I began, forcing him to remain in there for the duration of the conflict. During this period, he stayed at the Laren artists' colony, where he met Bart van der Leck and Theo van Doesburg, who were both undergoing their own personal journeys toward abstraction. Van der Leck's use of only primary colors in his art greatly influenced Mondrian. After a meeting with Van der Leck in 1916, Mondrian wrote, "My technique which was more or less Cubist, and therefore more or less pictorial, came under the influence of his precise method." With Van Doesburg, Mondrian founded De Stijl (The Style), a journal of the De Stijl Group, in which he first published essays defining his theory, which he called neoplasticism. Mondrian published "De Nieuwe Beelding in de schilderkunst" ("The New Plastic in Painting") in twelve installments during 1917 and 1918. This was his first major attempt to express his artistic theory in writing. Mondrian's best and most-often quoted expression of this theory, however, comes from a letter he wrote to H. P. Bremmer in 1914: I construct lines and color combinations on a flat surface, in order to express general beauty with the utmost awareness. Nature (or, that which I see) inspires me, puts me, as with any painter, in an emotional state so that an urge comes about to make something, but I want to come as close as possible to the truth and abstract everything from that, until I reach the foundation (still just an external foundation!) of things... I believe it is possible that, through horizontal and vertical lines constructed with awareness, but not with calculation, led by high intuition, and brought to harmony and rhythm, these basic forms of beauty, supplemented if necessary by other direct lines or curves, can become a work of art, as strong as it is true.

Question: Regine Velasquez was born in Tondo, Manila, on April 22, 1970. Her father, Gerardo Velasquez, was a construction estimator, and her mother, Teresita (nee Ansong), was a homemaker. The singer has three younger sisters, Cacai, Diane and Deca, and a younger brother, Jojo. The family moved to Hinundayan, Southern Leyte where Velasquez spent the early years of her life.

After winning Ang Bagong Kampeon, Velasquez was signed to OctoArts International (now PolyEast Records). She was introduced as 'Chona' Velasquez--her nickname--and recorded the single "Love Me Again", which was released in early 1986. However, the single was commercially unsuccessful. On February 16, 1986, at the behest of another OctoArts recording artist, Pops Fernandez, Velasquez was invited to appear on her live late night musical television show, The Penthouse Live! While she was rehearsing for the live show, the producer and talent manager Ronnie Henares showed interest and signed her. At the suggestion of Fernandez's husband and the show's co-host, Martin Nievera, Velasquez adopted the stage name "Regine". Under Henares' management, Velasquez was introduced to the head of VIVA Records, Vicente del Rosario Jr., who signed her and started production of her debut album. Del Rosario enlisted top songwriters, including Joaquin Francisco Sanchez, Vehnee Saturno and Christine Bendebel. He and Henares, who were both serving as executive producers, planned to market Velasquez as one of their main female pop artists, hoping to attain commercial success as they had done with Nora Aunor and Sharon Cuneta. After Velasquez completed her debut album, Regine, VIVA released the lead single "Kung Maibabalik Ko Lang" in 1987. Despite a weak start, the album gained mainstream appeal after Velasquez's promotional appearances on the ABS-CBN television variety shows Triple Treat and Teen Pan Alley. The album produced two more singles--"Urong Sulong" and "Isang Lahi". Two years after the release of her debut album, Velasquez represented the Philippines in the 1989 Asia Pacific Singing Contest. She was initially apprehensive and skeptical of the idea of participating in another competition at that stage in her career. At Henares' urging she agreed to compete and won the contest in Hong Kong, performing the songs "You'll Never Walk Alone" from the 1945 Rodgers and Hammerstein musical Carousel and "And I Am Telling You I'm Not Going" from the musical Dreamgirls.
