    Are we looking for a single answer or is it two separate questions? – rhsquared Sep 14 at 8:04

    If they're not part of the same puzzle, they should probably be posted separately. – 3D1T0R Sep 14 at 16:19

2B/37 (base 16) = 43/55 (base 10) = 43*4/55*4(base 10) = 172/220 (base 10) = AC/DC (base 16)

    I think it is just 2 separate questions :D – Kevin L Sep 14 at 8:58

    So the real challenge is for the OP to accept both answers. – Mr Lister Sep 14 at 12:47

    @MrLister I can't even tell which answer was first any more! – Anush Sep 14 at 14:18

    @Anush this answer was first by a little over a minute. You can see exact timestamps by hovering over the "Answered X hours ago" text. – David Starkey Sep 14 at 14:20

    Is it weird that I'm bothered by the unnecessary conversion to base 10 and back? I mean, hex is just another format for representing integers... Then again, it does help make this answer a little more clear. +1 either way for the clever solution. – Nic Hartley Sep 14 at 21:08

For B)

It was John Cage
91 x (pi) / 216000 rad will give 4'33"
John composed the piece 4'33"
