Great topic Knucis!
My favorite epic composers include James Horner, Howard Shore, John Williams, James Newton Howard, Ennio Morricone, who I saw perform with his orchestra last november and most notably Hans Zimmer, whose live show I was also privileged to see just last month. The latter was one of the most incredible live concerts I've been to and I've been to many. It was an overwhelming experience to see over 60 people on the stage that night, people who have perfectly mastered their instruments and they're able to create stunning harmonies and rhythms with such preciseness and feel and they're right there sending it straight to you. Combined with spectacular visuals and with one of the greatest rock guitarists of our era Guthrie Govan on the stage, I loved every second.
