Download or read book Here There and Everywhere written by Geoff Emerick and published by Penguin. This book was released on 2006-03-16 with total page 658 pages. Available in PDF, EPUB and Kindle. Book excerpt: An all-access, firsthand account of the life and music of one of history's most beloved bands--from an original mastering engineer at Abbey Road Geoff Emerick became an assistant engineer at the legendary Abbey Road Studios in 1962 at age fifteen, and was present as a new band called the Beatles recorded their first songs. He later worked with the Beatles as they recorded their singles “She Loves You” and “I Want to Hold Your Hand,” the songs that would propel them to international superstardom. In 1964 he would witness the transformation of this young and playful group from Liverpool into professional, polished musicians as they put to tape classic songs such as “Eight Days A Week” and “I Feel Fine.” Then, in 1966, at age nineteen, Geoff Emerick became the Beatles’ chief engineer, the man responsible for their distinctive sound as they recorded the classic album Revolver, in which they pioneered innovative recording techniques that changed the course of rock history. Emerick would also engineer the monumental Sgt. Pepper and Abbey Road albums, considered by many the greatest rock recordings of all time. In Here, There and Everywhere he reveals the creative process of the band in the studio, and describes how he achieved the sounds on their most famous songs. Emerick also brings to light the personal dynamics of the band, from the relentless (and increasingly mean-spirited) competition between Lennon and McCartney to the infighting and frustration that eventually brought a bitter end to the greatest rock band the world has ever known.

Download or read book Ferdydurke written by Witold Gombrowicz and published by Yale University Press. This book was released on 2012-04-24 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this bitterly funny novel by the renowned Polish author Witold Gombrowicz, a writer finds himself tossed into a chaotic world of schoolboys by a diabolical professor who wishes to reduce him to childishness. Originally published in Poland in 1937, Ferdydurke became an instant literary sensation and catapulted the young author to fame. Deemed scandalous and subversive by Nazis, Stalinists, and the Polish Communist regime in turn, the novel (as well as all of Gombrowicz's other works) was officially banned in Poland for decades. It has nonetheless remained one of the most influential works of twentieth-century European literature. Ferdydurke is translated here directly from the Polish for the first time. Danuta Borchardt deftly captures Gombrowicz's playful and idiosyncratic style, and she allows English speakers to experience fully the masterpiece of a writer whom Milan Kundera describes as “one of the great novelists of our century.”
