Hello, I was browsing Bob Ludwig wikipedia page and found out this picture.

i hear so much about him and when i look at his client list it's like war and peace, but what is it that makes him so good? I heard two different albums of a band, one mastered by bob and the earlier album was someone else, and all i could tell was that bob cranked it really loud and it was less open than the earlier album(but of course it would sound good on the radio...yippie).
