If you're into recent indyish bands (e.g., Arcade Fire, Cat Power, Decemberists, Modest Mouse, Neutral Milk Hotel, etc, -- plus compatible classics like Dylan and Neil Young), check out the concert archives of Owl and Bear. BUNCHES of shows, all in lossless formats, so large on the drive and you'll need a real media player (hardware or software; I recommend VideoLAN's VLC player, which covers all the major OSes) or else something to convert the FLAC and SHN files to MP3 (I use dbPowerAmp for this and recommend it).
Enjoy!
Enjoy!
