Summoning is an epic atmospheric black metal band from Vienna, Austria. Their style has been described as Tolkien black metal - not without reason, for the lyrics on most of the albums they have published deal with the mythological world of J.R.R. Tolkien. The notable exception being Stronghold, which takes its lyrical content from many of Tolkien's poems rather than directly from his novels.
Summoning was formed somewhere in 1993 by Silenius (Michael Gregor)
