Back OT:
I just downloaded the entire Led Zeppelin collection in HD 196Hz/24bit.
This is quite different from CD resolution which is typically 44Hz/16bit on anything from the "Redbook" catalog.
I remember when my dad first heard "Good Times, Bad Times" from the initial track on the first Led Zeppelin album played on our low quality RCA monaural, single speaker record player. I had borrowed the album from a "friend" and I wanted for him to hear it. I was fourteen and being born in 1926, he was forty three. He had already listened to and taught me a few Beatles songs on guitar growing up.
He was a musician and quite immune to the "normal" father reaction of being pissed of and disgusted with sixties rock music.
His eyes were size of saucers hearing Led Zeppelin for the first time and he just said, "This is different. I like it!"
He did not like the whole thing and he thought the singer was prissy (but so did I, now, I think of Robert Plant as the most incredibly unbridled emo singer in history - still like him), but any of the bluesy sounding tracks my dad liked.
A week later he was teaching me how to play my guitar using bar chords, like Jimmy Page was doing.
Having these albums in this high-resolution format has brought back some pleasant memories of my father.
