Thanks MNDude! Hard to dismiss your linked article as not being related to this attack, however the post I’m seeking specifically mentions the death metal concert. That is was stuck in my head.
Also located these articles, there may have been a thread on Thursday but if so I haven’t seen it:

The US-led coalition in Syria was apparently told by Iraqi security sources that 24 extremists were involved in the terror operation planned in the ISIS capital Raqqa and it would involve 19 attackers including five others including bombmakers and planners.
No detail was given of when or where an attack might take place.
But Islamic State group leader Abu Bakr al-Baghdadi was said to have ordered his followers to immediately launch gun and bomb attacks and take hostages inside the countries of the coalition fighting them in Iraq and Syria.

According to Channel 2, Israel had no advance warning of the Paris attacks but within hours of the assaults gave France details on some of the Islamic State militants believed to have carried them out.
Citing an unnamed senior Israeli official, Channel 2 said Israel saw a “clear operational link” between the Paris attacks, Thursday’s Beirut suicide bombings and the Oct. 31 downing of a Russian airliner in the Egyptian Sinai.
