I have the 6-6 Indy concert and am going to record the 6-8 concert tomorrow. I use Replay Radio
http://www.replay-radio.com
You can download it and try it for free (no credit card required). If you don't buy it after the trial, it just dies. If you want to buy it, it's $30. They also have a good MP3 editor for $10 (also with a free trial). I don't know if it'll work with dial-up, but I've gotten excellent results with broadband (use MP3, NOT WAV). It's VERY easy to use. Try it. Note that you MUST leave your computer on with the program open or it won't turn on. Also, I recommend setting it to record at least 1/2 hour before the concert and allow an extra 45min-1hour after the scheduled time, as they don't always run on time.
Editing out the extra long crowd noise (primarily at the end before encores), Radio Margaritaville DJ, and non-Jimmy music from intermission and inserting breaks between songs at the right place takes several hours. Figure on 2 CD's.
NOTE: I have seen sources that show the concert starting at 8 ET and 9 ET, so allow for the earlier time if you want to be sure you get it. With MP3 even 4 hours or so won't take up much hard drive space.
If you don't get it, let me know and I'll send you copies. It will be next week before I can get to the editing/jewel box inserts, though.
