Gavin Aung Than, an Australian graphic designer turned cartoonist, started the weekly Zen Pencils blog in February 2012. He describes his motivation for launching Zen Pencils: "I was working in the boring corporate graphic design industry for eight years before finally quitting at the end of 2011 to pursue my passion for illustration and cartooning. At my old job, when my boss wasn't looking, I would waste time reading Wikipedia pages, mainly biographies about people whose lives were a lot more interesting than mine. Their stories and quotes eventually inspired me to leave my job to focus on what I really wanted to do. The idea of taking these inspiring quotes, combining them with my love of drawing and sharing them with others led to the creation of Zen Pencils." "Zen Pencils deftly blends the inspired thoughts of our great creative and moral thinkers with its own fresh visual wit. Because these work as pithy history lessons illuminating timeless human truths, it's no wonder Gavin's engaging comics go viral!" Michael Cavna, Washington Post's Comic Riffs "Sometimes all it takes is a clear, original vision and a talented hand. Gavin Aung Than and his genius of Zen Pencils gives us that together, and so much more." -Chris Hadfield, retired astronaut and former Commander of the International Space Station "If you read this book and don't get a lump in your throat and a stirring in your heart at least once, check your pulse. You're dead." Philip Plait, The Bad Astronomer "Gavin has the amazing ability to make words and ideas come alive. He teaches, inspires, and brings a whole new level of creativity to the quotes that hold a special place in our hearts." Bren Brown, Ph.D., LMSW Author of the No. 1 New York Times Bestseller, Daring Greatly "Zen Pencils is a visual demonstration of joy and courage. Buy it for inspiration, and keep it for regular reminders of living bigger." Chris Guillebeau, New York Times Bestselling Author of The $100 Startup

Esta edición surge de un libro de Umberto Pérez que la Secretaría de Cultura publicó en 2007 bajo el título Bogotá, epicentro del rock entre 1957 y 1975. La obra original se amplió con artículos de Luis Daniel Vega, un par de textos de Ricardo Durán y Jaime Andrés Monsalve -dos invitados de lujo-, y un nuevo título tan sólido como granizo: Una idea descabellada. Instantáneas del rock en Bogotá (1957-1975). Los investigadores, escritores y sobre todo melómanos que en este compendio no solo interpretan el papel de relatores sino a la vez el de alquimistas y reinventores, cuentan cómo el rock capitalino, más que un género con cuadrículas fijas, es una creación colectiva, dispar y con la mira puesta en muchos lados. Como la ciudad misma. Cuentan de bandas de rock que se desmantelaron y luego dieron paso a otras nuevas con una rapidez extrema. El rock bogotano convirtió el esmog y la polución en una dorada y preciosa serie de obras musicales.
