2017-03-14: Finalmente percebi porque soa tão bem...

... o remaster para o documentário Eight Days a Week e o CD correspondente (que é baseado em dois concertos numa sala americana de nome Hollywood Bowl). Recordo-me claramente de como soava o vinil de 1977 que uma prima minha tinha e ao voltar a ouvir o remaster cheguei a pensar que o GH era um picuinhas ao dizer (na Anthology) que não se conseguia ouvir a tocar e que toda aquela histeria e gritaria eram insuportáveis. Mas não. A questão é que os concertos são os mesmos mas o som foi todo "reconstruído" (para remover o barulho do público). 

Para saber como leiam o artigo seguinte todo, vale definitivamente a pena:

Citando:
"THE BEATLES’ REMARKABLE catalog includes just one official live album, and the group’s immense popularity made it unlistenable. The Beatles at the Hollywood Bowl, recorded in 1964 and 1965 but not released until 1977, was always a frustrating listen. Try as you might, you simply cannot hear much music above the fan-belt squeal of 10,000 Beatlemaniacs.

You can’t blame the Fab Four, nor their legendary producer George Martin. Martin did what he could with the three-track tapes, but the limitations of 1970s technology did little to elevate the music above the din. Boosting the high frequencies—the snap of Ringo Starr’s hi-hat, the shimmer and chime of George Harrison’s guitar—only made the racket made by all those fans even louder.

All of which makes the remastered version of Live at the Hollywood Bowl especially impressive. The do-over, which coincided with the August release of Ron Howard’s documentary film Eight Days a Week, squeezes astonishing clarity out of the source tapes. You can finally hear an exceptionally tight band grinding out infectious blues-based rock propelled by a driving beat, wailing guitars, and raspy vocals. This album never sounded so lucid, present, or weighty."
