For favorites, I'd have to go with Blink of An Eye; The Window Purpose (Wolverine), virtually any Opeth cover, Roll the Bones (Rush), Discipline (King Crimson), the Magna Carta Emerson Lake & Palmer tribute, the seminal A Love Supreme (Trane), Blue Parade (Sarah Slean), and Eat a Peach (The Allman Brothers Band). All of them are darn cool, but a few of them mark some personally-riveting memory.
