Paul Klee (German: [paUl 'kle:]; 18 December 1879 - 29 June 1940) was a Swiss German artist. His highly individual style was influenced by movements in art that included Expressionism, Cubism, and Surrealism. Klee was a natural draftsman who experimented with and eventually deeply explored color theory, writing about it extensively; his lectures Writings on Form and Design Theory (Schriften zur Form und Gestaltungslehre), published in English as the Paul Klee Notebooks, are held to be as important for modern art as Leonardo da Vinci's A Treatise on Painting for the Renaissance. He and his colleague, Russian painter Wassily Kandinsky, both taught at the Bauhaus school of art, design and architecture.
During his twelve-day educational trip to Tunis in April 1914 Klee produced with Macke and Moilliet watercolor paintings, which implement the strong light and color stimulus of the North African countryside in the fashion of Paul Cezanne and Robert Delaunays' cubistic form concepts. The aim was not to imitate nature, but to create compositions analogous to nature's formative principle, as in the works In den Hausern von Saint-Germain (In the Houses of Saint-Germain) and Strassencafe (Streetcafe). Klee conveyed the scenery in a grid, so that it dissolves into colored harmony. He also created abstract works in that period such as Abstract and Farbige Kreise durch Farbbander verbunden (Colored Circles Tied Through Inked Ribbons). He never abandoned the object; a permanent segregation never took place. It took over ten years that Klee worked on experiments and analysis of the color, resulting to an independent artificial work, whereby his design ideas were based on the colorful oriental world.  Fohn im Marc'schen Garten (Foehn at Marc's Garden) was made after the Turin trip. It indicates the relations between color and the stimulus of Macke and Delaunay. Although elements of the garden are clearly visible, a further steering towards abstraction is noticeable. In his diary Klee wrote the following note at that time:  In the large molding pit are lying ruins, on which one partially hangs. They provide the material for the abstraction. [...] The terrible the world, the abstract the art, while a happy world produces secularistic art.  Under the impression of his military service he created the painting Trauerblumen (Velvetbells) in 1917, which, with its graphical signs, vegetal and phantastic shapes, is a forerunner of his future works, harmonically combining graphic, color and object. For the first time birds appear in the pictures, such as in Blumenmythos (Flower Myth) from 1918, mirroring the flying and falling planes he saw in Gersthofen, and the photographed plane crashes.  In the 1918 watercolor painting Einst dem Grau der Nacht enttaucht, a compositional implemented poem, possible written by Klee, he incorporated letters in small, in terms of color separated squares, cutting off the first verse from the second one with silver paper. At the top of the cardboard, which carries the picture, the verses are inscribed in manuscript form. Here, Klee did not lean on Delaunay's colors, but on Marc's, although the picture content of both painters does not correspond with each other. Herwarth Walden, Klee's art dealer, saw in them a "Wachablosung" (changing of the guard) of his art. Since 1919 he often used oil colors, with which he combined watercolors and colored pencil. The Villa R (Kunstmuseum Basel) from 1919 unites visible realities such as sun, moon, mountains, trees and architectures, as well as surreal pledges and sentiment readings.

What else can you tell me about the Mystical-abstract period?

Answer the question at the end by quoting:

The Buggles were an English new wave band formed in London, England in 1977 by singer and bassist Trevor Horn and keyboardist Geoffrey Downes. They are best known for their 1979 debut single "Video Killed the Radio Star" that topped the UK Singles Chart and reached number one in 15 other countries. The duo released their first album, The Age of Plastic, in January 1980 with "Video Killed the Radio Star" as its lead single. Soon after the album's release, Horn and Downes joined the progressive rock band
In early 1981, following the disbanding of Yes, Downes and Horn reconvened at Sarm East Studios to record The Buggles' second studio album, Adventures in Modern Recording. However, Downes left the group on the day the recording of the album was meant to begin to help form Asia with Howe citing musical differences. Horn was angry that Island Records renegotiated publishing terms for Downes to join Asia, but never did for Horn since, in his words, he was "washed up, career-wise". To fix this problem, Jill Sinclair made a deal with the French label Carrere, whose leader Claude Carrere, whom Horn described as a "very nice man", helped fund the album. Horn was now left to complete much of the album with several additional personnel.  Released in November 1981, Adventures in Modern Recording involved Horn experimenting with numerous production techniques, especially with the heavy use of sampling with the Fairlight CMI, with instruments from the computer such as the drums on "Inner City" and the big band jazz sounds on "Vermillion Sands". These same sampling techniques would later be used in records he produced such as Slave To The Rhythm by Grace Jones, Yes's 90125, Art of Noise's The Seduction of Claude Debussy and Frankie Goes To Hollywood's Welcome to the Pleasuredome. While the album garnered little attention in the United Kingdom, Horn recalled in 2010 that the album was a commercial success in France, and in the United States the album peaked at number 161 on the American Billboard 200. By the time of the album's release, when Horn was also producing ABC's album The Lexicon of Love, he decided to take Sinclair's advice that he always was meant to be a producer rather than a performer or songwriter, thus the performance of "Lenny" on a TV show in the Netherlands, with ABC as the backing band, marked the end of the Buggles. As Horn recalled when he was interviewed after the show:  "I'll never forget it because the guy said to me, 'well, things are not looking so good for you', and I said 'how do you mean?' And he said 'well, you know, your first record was a big hit now this record is number eleven, so your career is going downhill'. And I said 'well you know what? You see these guys, this is a band called ABC and I'm a producer now I don't really care about this stuff, I'm just doing it to promote the record. And I may be on the skids as an artist but things are looking up in other areas. End of interview. Fuck off.'"
