Many people here will know about these sites already, but for those who don't:
Mazzy Star has their own official FB page, here:
https://www.facebook.com/MazzyStarOfficial/?fref=ts
Hope Sandoval & the Warm Inventions have their own official FB page, here:
https://www.facebook.com/HopeSandovalWa ... ?ref=br_tf
The most active of the two above sites currently is the Warm Inventions one as Hope has a new
Warm Inventions album out. Welcome, unexpected things can appear on these FB sites, e.g. on Nov. 4, 2016, the band posted a short video of a Warm Inventions live rehearsal session. Hope's own "voice" seems apparent in some of the messages accompanying some FB posts. For instance, there are some humourous cat-themed messages which sound very much as if they were penned by cat-person Hope! She's also been known to very occasionally sign her name to FB posts.
This is in contrast to Hope's own "official website," http://www.hopesandoval.com/home.shtml , where Hope, as far as I know, has never posted any comment personally there herself. The webmaster there, a guy named Colin, has sometimes been a bit slow about keeping up with Hope's career. As a current example, over the past two weeks, 8 or 9 new interviews with Hope & Colm have appeared at various websites and have been posted here at mazzystar.free.fr. I checked hopsesandoval.com today, and the "What's New" section there has but one new interview posted, and it's not one of the best ones, either. Same thing happened re. Mazzy Star's 2013 interviews. The hopesandoval,com webmaster completely missed two-thirds of them, including the best 2013 interviews! On looking back through the site's "What's New" section entries from this year, it looks like all Hope's singles and collabs of this year got covered, which is good. But the bands' official FB sites seem more reliable sites to go to for keeping current with news on band activities. hopesandoval.com has an excellent photo gallery, especially of shots of HS&TWI on stage.
Also, there's a very popular Mazzy Star/Hope FB fan Group, here: https://www.facebook.com/groups/6071129794/
It currently has 2,700+ members. It's a closed group, which means you need to ask to join. I think this is mainly to screen out suspected spammers, and they apparently will reject people who appear to be too inactive on FB, e.g. people not already belonging to other groups, etc. It's a popular and very active site (the opposite of mazzystar.free.fr, which, in contrast is rather sleepy). Lots of people love FB these days, apparently. Mazzy Star's drummer, Keith Mitchell, is a member, and has made some occasional helpful posts and comments there. There are a few other apparent band "insiders" or relatives there too, one of Hope's cousins, for instance, and a member named "Bad Roison" (Irish for "Red Boat") who sometimes offers what appears to be inside info or new info such as Colm's apparent, but low-key involvement in creating videos for both bands.
But "sleepy" mazzystar.free.fr still has a huge advantage over the FB fan group in some ways, imo, and remains a very valuable site. The FB Group has no organization to its content whatsoever. It consists of one long series of random posts to scroll through. Specialized informative resource threads that exist at mazzystar.free such as the Bootlegs List, the various interviews archives threads, or band history thread, couldn't exist on the jumbled, chaotic FB site.
Also, there are some official youtube channels, such as Hope Sandoval & the Warm Inventions' one, here:
https://www.youtube.com/channel/UCUUv9h ... Q/featured
Check out their "playlists" there.
And Mazzy Star's official youtube Channel: https://www.youtube.com/user/MazzyStarVEVO
where a number of their official videos of recent years are posted.
And this seems to be an official yt Channel where some official videos of both Mazzy Star and HS&TWI have been posted, including one for HS&TWI's 2016 single, "Isn't It True." https://www.youtube.com/channel/UCiHpAu ... A_Ggn1I2RQ
Plus, there's reason to suspect this video for Mazzy Star's "In the Kingdom" was made by Colm O'Cosoig under a pseudonym: https://www.youtube.com/watch?v=CrLIcnl1LfI
There are a couple of tumblr fan sites, mostly consisting of photo and GIF uploads submitted by multiple tumblr members. I think both these sites are operated by the same person. He's a good guy. I occasionally submit stuff there when I come across a new photo or video clip to share.
