From tips for evaluating recordings, to lively discussions of bootlegging, the history of recording formats, "most collected artists" and more, this informative and fun guide covers all the tracks. Garage sale hunters and web surfers alike will find over 20 categories with proven collector appeal - from vintage rock to Christmas music, soundtracks, and much more. Engaging essays and entries explore every medium ever used to transcribe music: the first vinyl 78s, 45s, 8-track cartridges, cassette tapes, LPs, CDs, MP3 and more, plus specialty items like colored vinyl. The guide describes the significance and collectibility of bootlegs, promos and imports, as well as 100 "most collected artists" from Elvis Presley to Bob Marley, and niche artists like Tim Buckley and Syd Barrett. Some artist entries include interviews with musicians and collectors, insights on rarities vs. regular releases, and helpful "what to look for" tips. Landmark labels collected for their own sake are also covered, such as Sun, Chess, and Motown. And for those who believe a recording is not collectible without its complete packaging, photo essays illustrate original inner album sleeves, accompanying stickers, pictures, posters, and other artwork.
