You can pre-order Metallica's Reading or Leeds festival shows for legal download in either mp3 or lossless FLAC versions from www.livemetallica.com. The mp3 version costs $8.95 (about £5), while the FLAC version is $11.65 (about £6). These prices save 10% on the post-tour prices. Look like bargains to me!
