Schubert, you are on a roll today putting Mahler and rock music in the same boat of ne'er-do-wells, eh?
Oh well, at he is in GOOD rock music company.
Mahler 3rd is unmatched on its turf in my book. Nothing else sucks me in as deeply as quickly and then takes me on an emotional roller coaster for as long and as well as that one, complete with tearing eyes along the way. It's an ethereal experience for sure, but it ain't "pretty".
"Suppers Ready" by Genesis is in the same ballpark but over in the progressive rock league and it does have some very pretty parts.
"Seventh Sojourn" album by The Moody Blues is in the same ballpark as well with some breathtakingly gorgeous parts. See my review here on A'gon for more about that.
