Greatest Musical Artist of the last 100 years Round 2 Group A

So the first round is over, the votes are in and probably the biggest shock being that Oasis are out, beaten by their idols.

Today marks the start of the next round, I've decided this round will also be group based being that there's still 66 contenders to whittle through, all the groups contain 4 artists except groups 9 & 10 which were randomly drawn to have the two remaining artists added in to make them both 5 each. As before the top 2 go through (in the event of a tie for 2nd both go through).

So here's the first of today's groups for you...

Neil Young
David Bowie
REM
Bob Marley
