Two questions

[pseudolongino]

Hi I'm new here i have two difficult questions.
I was searching for a blog i used to consult daily several years ago, many of you have probably heard of it, metrognome blogspot. It contained hundreds of live broadcast often in good quality sound, many concerts by steinberg, munch and similary icons from the sixties but also more recent ones such as dudamel etc.
I cannot find it anymore, the original url seems to be empty, there are 29 articles from 2013-2014 on a site rssing, maybe an aggregator, but without the content, i don't even know how to contact the original creator of the blog and this material isn't even available on torrent or anything so I'd really like to know if someone republished that material or is it lost forever?
One concert i could never find even on that blog is a James Levine Mahler 8th. As you know, his RCA cycle misses 2th and 8th but the former is now available in two versions (that i know of), the latter is not. I managed to found a tanglewood performance with decent sonics but I've read of a magnificent philharmonia reading in London. Can anybody help me locate this and other live broadcast from the past?
The metrognome left a big hole and i don't know of any other site filling it.
Thanks

Looks like Internet Archive https://web.archive.org/web/20170607041443/http://metrognomemusic.blogspot.com/ have captured some of the blog pages but no links to any media.

You could try searching their audio archive https://archive.org/details/audio

If you join the google group symphonyshare you'll be able to get many of metrognome's uploads.
