TIME Are you bigger music fans now?
BILL GATES: I’ve always been a music fan. Paul [Allen, Microsoft’s co-founder] played guitar and made sure I knew all the Jimi Hendrix songs. He’s a real music nut. Not many people create a music museum. [Allen founded Seattle’s Experience Music Project.]
BONO.: You couldn’t not listen to music if Paul Allen was your partner. So Jimi Hendrix helped form [slipping into a monster-movie voice] "the Brain of Bill!"
BILL GATES: Paul would always say, "Are you experienced?" And it would mean different things at different times.
