It has come to my attention that I should devote some small amount of time to the file types used on this blog. This really should have been in my introductory post, but was not. Ah well.
In any case, the files as downloaded are .RAR, which means you will need a program called winRAR to open them. You can obtain this program for free here: http://www.rarlab.com/download.htm
The .RAR files are a compressed format, which allows me to upload them as three links for an entire lossless-quality CD. Speaking of lossless quality, the tracks are uncompressed .WAV files. These have typically been downloaded as FLAC, converted to WAV, edited using the Audacity program, then output again as WAVs. This preserves the high quality of the audio. If there is significant demand for mp3 versions, I can facilitate mp3 links, though they probably will not be available simultaneous to the WAV format.
I find WAV to be the best option, as it eschews the challenges associated with FLAC by the average user (specific software needed to convert so that it can be listened to or loaded onto an audio device), but manages to retain the very high quality sound. These releases are not directed at the collectors, as they will almost certainly have these tracks without my edits (splicing, fades, etc.) in a "purer" version. Instead, these CDs are aimed at folks like myself who want a pleasant listening experience on a single volume that spans a particular series of sessions, concerts, tours, etc. And of those, there is much to come.
Hopefully that clears things up. If anyone has any other questions about technical issues, please feel free to post them below and I'll respond as time allows.
