Two big names in the world of Heavy Metal festivals are broadcasting at least parts of the big festival line-ups - both totally for free!
First to go is the Graspop Metal Meeting which gives you the chance to see some bands on two different channels. You need to have Silverlight installed on your device to be able to watch this.
Underneath of the stream window you can check out the schedule of the bands that will be streamed - check for the green or partly green marked fields in the overview. Those bands will be shown, or at least some tracks from their set.
Keep in mind that the schedule changes over the day - bands may be added to the broadcast list very shortly (just for example: I saw two changes in the few moments of time I took to write this article - so check back often :-) At the moment I'm typing this these bands are confirmed for today (Saturday 20th June)
Update 2015/06/22: It's sadly over but there's still a chance to see stuff from the Graspop Metal Meeting at the concert video archive that has been opened up. Go and watch it while it's up!
The next one to check out is the Hellfest from France. There it's a bit more complicated. Leave the guy with the gray face on the top of the page behind and scroll to the six pictures below. Hover over the stream you desire (they are sorted with the date and stage name) to see the bands that are scheduled for the live stream. One more click and you can watch it. Or even better: see the bands you want directly here on my page. Great to see the people from Arte allow embeding streams to other sites. Thanks for that! The streams start at 17:15h today.
Update 2015/06/22: It's sad to see the festival is already over now. :-( But wait, some stuff can be seen again (or for the first time if you missed it out). The Hellfest livestream page is now a archive of some of the festival performances. :-) You can watch shows from Sodom, Children of Bodom, Scorpions, Faith no more and many, many more on the linked page. Enjoy (again)!
This is what is confirmed for the Altar & Temple stage at the moment for this very saturday:
This overview shows what will be shown from the main stage:
Killing Joke 19:45
Faith No More 21:45
