Question:
Autechre () are an English electronic music duo consisting of Rob Brown and Sean Booth, both from Rochdale, Greater Manchester. Formed in 1987, they are one of the most popular acts signed to UK electronic label Warp Records, through which all of Autechre's full-length albums have been released beginning in 1993 with Incunabula. They have also worked closely with the label Skam. The music of Autechre has shifted gradually throughout their career, from their earlier work's roots in techno, electro, and hip hop to later albums often considered experimental in nature, featuring complex drum programming, subdued melodies, and few stylistic conventions.
The new millennium brought about a drastic change in Autechre's style, demonstrated by Confield (2001) and Draft 7.30 (2003), as well as the Gantz Graf EP (2002). The title track from Gantz Graf inspired an iconic video by British designer Alex Rutterford, featuring an object (or an agglomeration of objects) synchronized to the music as it morphs, pulsates, shakes, and finally dissolves. Rutterford, who had previously created an unofficial video for the Tri Repetae track "Eutow" as part of the Channel 4 music programme Lo-Fi in 2001, claimed the idea for the "Gantz Graf" video came during one of his LSD trips. The second Autechre Peel session EP was also released in 2002, containing four tracks broadcast in 1999, named by John Peel himself. Autechre released two collaborative albums with Andrew M. McKenzie's Hafler Trio collective during the following three years (see collaborations).  The reactions by both professional critics and fans to the release of Confield were mixed, though generally positive. According to Sean Booth, "most of Confield came out of experiments with Max that weren't really applicable in a club environment." In contrast, 2003's Draft 7.30 was seen by some as an easier record to grasp. Booth stated in an interview around the release of Draft 7.30 that "[rhythm] doesn't seem to limit us in the way it did when we first started. Now I think we just get it, we're totally fluent in it and can be more expressive."  Untilted (a play on the word "untitled"), the duo's eighth album, was released in 2005. It roughly continued the sound of their previous two LPs, though featured compositions that mutated greatly during their duration, typically alternating between passages of ambience and heavily processed, precise beats, such as on "Ipacial Section". Its final track, "Sublimit", is at almost sixteen minutes Autechre's longest composition to feature on any of their albums until 2016's elseq 1-5. The release of Untilted was followed by a two-month tour that took the group around Europe, America and Japan, but withdrew them from studio work for an unusual length of time. The outcome of this, coupled with a forced change in studio setup, was a gap of three years between releases, longer than ever before.

Question:
Anton Friedrich Wilhelm (von) Webern (German: ['anton 've:ban] ( listen); 3 December 1883 - 15 September 1945) was an Austrian composer and conductor. Along with his mentor Arnold Schoenberg and his colleague Alban Berg, Webern was in the core of those in the circle of the Second Viennese School, including Ernst Krenek and Theodor W. Adorno. As an exponent of atonality and twelve-tone technique, Webern exerted influence on contemporaries Luigi Dallapiccola, Krenek, and even Schoenberg himself.
Webern published little of his early work in particular; like Brahms, though perhaps for not entirely the same reasons, Webern was characteristically meticulous and revised extensively. Many juvenilia remained unknown until the work and findings of the Moldenhauers in the 1960s, effectively obscuring and undermining formative facets of Webern's musical identity, highly significant even more so in the case of an innovator whose music was crucially marked by rapid stylistic shifts. Thus when Boulez first oversaw a project to record "all" of Webern's music, not including the juvenilia, the results fit on three rather than six CDs.  Webern's earliest works consist primarily of lieder, the genre that most belies his roots in Romanticism, specifically German Romanticism; one in which the music yields brief but explicit, potent, and spoken meaning manifested only latently or programmatically in purely instrumental genres; one marked by significant intimacy and lyricism; and one which often associates nature, especially landscapes, with themes of homesickness, solace, wistful yearning, distance, utopia, and belonging. Robert Schumann's "Mondnacht" is an iconic example; Eichendorff, whose lyric poetry inspired it, is not far removed from the poets (e.g., Richard Dehmel, Gustav Falke, Theodor Storm) whose work inspired Webern and his contemporaries Alban Berg, Max Reger, Arnold Schoenberg, Richard Strauss, Hugo Wolf, and Alexander Zemlinsky. Wolf's Morike-Lieder were especially influential on Webern's efforts from this period. But well beyond these lieder alone, all of Webern's music may be said to possess such concerns and qualities, as is evident from his sketches, albeit in an increasingly symbolic, abstract, spare, introverted, and idealized manner.  Other works include the orchestral tone poem Im Sommerwind (1904) and the Langsamer Satz (1905) for string quartet.  Webern's first piece after completing his studies with Schoenberg was the Passacaglia for orchestra (1908). Harmonically, it is a step forward into a more advanced language, and the orchestration is somewhat more distinctive than his earlier orchestral work. However, it bears little relation to the fully mature works he is best known for today. One element that is typical is the form itself: the passacaglia is a form which dates back to the 17th century, and a distinguishing feature of Webern's later work was to be the use of traditional compositional techniques (especially canons) and forms (the Symphony, the Concerto, the String Trio, and String Quartet, and the piano and orchestral Variations) in a modern harmonic and melodic language.
