200 MB for a two hour concert simply must have some audio compression to compromise the music. The most common compression schemes for full WAV files (SHN and FLAC) can sometimes get over 50 per cent reduction in size, but that is generally when the music is sparse enough to allow for it. And Pearl Jam is not exactly known for a lot of air between the music. Since a one hour CD generally contains about 600 MB of music, I'd expect a two hour rock concert compressed with a "lossless" compression scheme to be more like 600 MB.
I'd say that Pearl Jam compromized the audio quality so the download time was a reasonable size for the average downloader. If the same concert were available as a CD, which Pearl Jam has done in the past, I'd expect it to have better sound quality.
