Why would anyone want or 5 or more times the same CD/LP?
Well in my case I don't make a habit of it. However, if an LP is out of print and I have to buy it used, another copy might pop up that is in better condition than the other copy(ies) I have. Such is the case with the Lou Reed lp I mentioned on my list. It's one of my favorites by him and its pretty difficult to find. Most were cut-outs and on my 5th purchase I was finally able to get a clean copy that wasn't a cut-out.
As for the Richard Thompson lp on my list. If you like his music and you haven't heard this lp then its a must have in my opinion. It's a two lp set. The first lp is all of the previously released "I Want to See the Bright Lights Tonight." The second lp side one, offers some rare studio recordings/outtakes. The version of "Ballad of Easy Rider" featuring Sandy Denny will bring you to tears (shortly after I purchased my first copy she passed away). Side four offers two live cuts, "Calvary Cross" and "Night Comes In." Anyone interested in why many feel Richard Thompson is one of the greatest (and sometimes overlooked) guitarists of our time just needs to listen to these two tracks to find out.
