input: With Cain on board, the band began writing material that would eventually lead up to Journey's biggest studio album, "Escape". Recording sessions began in April 1981, and lasted until the middle of June. Escape was released on July 31, 1981, and immediately the album became a mainstream success. The album, which has thus far sold nine times platinum, went to number one on the album charts later that year, and included three top-ten hits: "Who's Cryin' Now", "Don't Stop Believin'" and "Open Arms". The last is Journey's highest-charting single to date, staying at No. 2 for six consecutive weeks and ranking at No.34 on Billboard's 1982 year-end Hot 100. MTV videotaped one of their two sold-out shows in Houston on November 6, 1981, in front of over 20,000 fans.  Capitalizing on their success, the band recorded radio commercials for Budweiser and sold rights to their likenesses and music for use in two video games: the Journey arcade game by Bally/Midway and Journey Escape by Data Age for the Atari 2600.  This success was met with criticism. The 1983 Rolling Stone Record Guide gave each of the band's albums only one star, with Dave Marsh writing that "Journey was a dead end for San Francisco area rock." Marsh later would anoint Escape as one of the worst number-one albums of all time.  Journey's next album, Frontiers (1983), continued their commercial success, reaching No. 2 on the album charts, selling nearly six million copies. The album generated four Top 40 hits, "Separate Ways (Worlds Apart)", which reached No. 8, "Faithfully", which reached No. 12, "Send Her My Love" and "After the Fall", both of which reached No. 23. By this time, Journey had become one of the top touring and recording bands in the world. During the subsequent stadium tour, the band contracted with NFL Films to record a video documentary of their life on the road, Frontiers and Beyond. Scenes from the documentary were shot at JFK Stadium in Philadelphia, Pennsylvania with more than 80,000 fans in attendance.

Question: Pieter Cornelis "Piet" Mondriaan, after 1906 Mondrian (; Dutch: ['pit 'mondrija:n], later ['mondrijan]; 7 March 1872 - 1 February 1944), was a Dutch painter and theoretician who is regarded as one of the greatest artists of the 20th century. He is known for being one of the pioneers of 20th century abstract art, as he changed his artistic direction from figurative painting to an increasingly abstract style, until he reached a point where his artistic vocabulary was reduced to simple geometric elements. Mondrian's art was highly utopian and was concerned with a search for universal values and aesthetics. He proclaimed in 1914: Art is higher than reality and has no direct relation to reality.

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.
