FSSD meaning in General ?

First Strike Still Deadly is the ninth studio album by Testament, released in 2001. It consists of re-recorded songs released on The Legacy and The New Order, as well as a re-recording of "Reign of Terror", which was originally on Legacy's Demo 1 and appeared as a B-side from the "Trial by Fire" single; the latter version also appeared on the 1993 EP Return to the Apocalyptic City. On some Japanese versions of this release, a different cover is present, and the disc is an enhanced CD and includes a bonus documentary with live clips of various incarnations of the band.

First Strike Still Deadly saw a Testament reunion with three former or current members (guitarist Alex Skolnick, bassist Steve DiGiorgio and drummer John Tempesta) as well as their original singer Steve "Zetro" Souza. Souza, Skolnick and Tempesta did not officially rejoin Testament at the time of its recording, though Skolnick did in 2005 and is still a member of the band to this day. First Strike Still Deadly was also the last Testament album with bassist DiGiorgio before his return in 2014.
