Best Of: Questlove / Tuba Player Richard Antoine White

In his new book, 'Music is History,' Roots co-founder Ahmir "Questlove" Thompson moves year-by-year through his life, writing about memories and turning points, and the songs he was listening to at the time.

Richard Antoine White spent his early childhood in poverty in Baltimore, at times sleeping in abandoned houses. He's now principal tubist in the Santa Fe Symphony and the New Mexico Philharmonic. He recounts his triumph over adversity in a new memoir called 'I'm Possible.'
