hello...my name is joel and i am a relatively new fan...i havea few ?'s for anyone who is kind enough to answer...i was wondering if the re-releases of such titles as "till we have faces," "good dog, bad dog," were any different from the original releases (i.e. different mixes or so-called re-mastering) or was the intent of the re-issues just to get the same music out to more people...im going to purchase the titles that i dont already have online so i just want to know which releases if any were different from each other...also if anyone had some recommedations...that would be wonderful...the only stuff i have is films for radio, eve, asr, and till we have faces(re-issue)
