Found the following article online, use it to answer the question: What is the first name of the person who depicted his models in highly fashionable clothing, often with rounded—almost sculpted—facial features, some of which deviated from natural representation?  Portrait of a Lady (or Portrait of a Woman) is a small oil-on-oak panel painting executed around 1460 by the Netherlandish painter Rogier van der Weyden. The composition is built from the geometric shapes that form the lines of the woman's veil, neckline, face, and arms, and by the fall of the light that illuminates her face and headdress. The vivid contrasts of darkness and light enhance the almost unnatural beauty and Gothic elegance of the model. Van der Weyden was preoccupied by commissioned portraiture towards the end of his life and was highly regarded by later generations of painters for his penetrating evocations of character. In this work, the woman's humility and reserved demeanour are conveyed through her fragile physique, lowered eyes and tightly grasped fingers. She is slender and depicted according to the Gothic ideal of elongated features, indicated by her narrow shoulders, tightly pinned hair, high forehead and the elaborate frame set by the headdress. It is the only known portrait of a woman accepted as an autograph work by van der Weyden, yet the sitter's name is not recorded and he did not title the work. Although van der Weyden did not adhere to the conventions of idealisation, he generally sought to flatter his sitters. He depicted his models in highly fashionable clothing, often with rounded—almost sculpted—facial features, some of which deviated from natural representation. He adapted his own aesthetic, and his portraits of women often bear a striking resemblance to each other.The painting has been in the National Gallery of Art in Washington, D.C. since donated in 1937, and is no. 34 in the de Vos catalogue raisonné of the artist. It has been described as "famous among all portraits of women of all schools".

Found the following article online, use it to answer the question: What is the name of the person who went into some detail about Rimsky-Korsakov's epiphany and turnaround regarding musical training, as well as his efforts to remedy this situation for himself?  The Five was among the myriad of subjects Tchaikovsky discussed with his benefactress, Nadezhda von Meck. By January 1878, when he wrote to Mrs. von Meck about its members, he had drifted far from their musical world and ideals. In addition, The Five's finest days had long passed. Despite considerable effort in writing operas and songs, Cui had become better known as a critic than as a composer, and even his critical efforts competed for time with his career as an army engineer and expert in the science of fortification. Balakirev had withdrawn completely from the musical scene, Mussorgsky was sinking ever deeper into alcoholism, and Borodin's creative activities increasingly took a back seat to his official duties as a professor of chemistry. Only Rimsky-Korsakov actively pursued a full-time musical career, and he was under increasing fire from his fellow nationalists for much the same reason as Tchaikovsky had been. Like Tchaikovsky, Rimsky-Korsakov had found that, for his own artistic growth to continue unabated, he had to study and master Western classical forms and techniques. Borodin called it "apostasy", adding, "Many are grieved at present by the fact that Korsakov has turned back, has thrown himself into a study of musical antiquity. I do not bemoan it. It is understandable...." Mussorgsky was harsher: "[T]he mighty kuchka had degenerated into soulless traitors."Tchaikovsky's analysis of each of The Five was unsparing. While at least some of his observations may seem distorted and prejudiced, he also mentions some details which ring clear and true. His diagnosis of Rimsky-Korsakov's creative crisis is very accurate. He also calls Mussorgsky the most gifted musically of the Five, though Tchaikovsky could not appreciate the forms Mussorgsky's originality took. Nonetheless, he badly underestimates Borodin's technique and gives Balakirev far less than his full due—all the more telling in light of Balakirev's help in conceiving and shaping Romeo and Juliet.Tchaikovsky wrote to Nadezhda von Meck that all...

Found the following article online, use it to answer the question: What is the name of the person who asserted that the concept, melodies, and lyrics of "Already Gone" and "Halo" are completely different?  Soon after composing "Halo", Tedder worked with Kelly Clarkson on her fourth studio album, All I Ever Wanted (2009), for which they wrote "Already Gone" together. When the song came out, critics noted a resemblance to Beyoncé's "Halo". Clarkson, however, initially stated that she was unaware of any similarities between the two songs. She eventually realized their resemblance when she listened to both recordings closely; the similarities are most notable in the backing tracks, which in both cases feature a melancholy piano, loud drums, and handclaps. Clarkson tried to prevent "Already Gone" from being included on All I Ever Wanted, but it was impossible to make last minute changes, as her album was already being printed when I Am... Sasha Fierce was released. She accused Tedder of using the same arrangement on both "Already Gone" and "Halo", and complained that people would, incorrectly, assume she was stealing it from Beyoncé.Clarkson was furious, and confronted Tedder on the phone. In response, Tedder commented that he would never give two artists the same musical arrangement, and that her criticism was "hurtful and absurd". He asserted that the concept, melodies, and lyrics of "Already Gone" and "Halo" are completely different. Calling "Already Gone" one of the best songs he had ever composed, Tedder challenged people to "listen [to the two ballads] and form their own opinions". Clarkson also tried to stop her label, RCA, from releasing "Already Gone" as a single because she respected Beyoncé, but they went against her will and released it. She said, "It's one of those things I have no control over. I already made my album. At this point, the record company can do whatever they want with it." Clarkson later told James Montgomery of MTV News that it was unfortunate "Already Gone" and "Halo" sound so similar, but noted that at least they have different vocal melodies.
