Certainly a unique Testament album; many of their best songs off of their first two albums are rerecorded in a much heavier style. With that said, you are probably better off getting The Legacy and The New Order before this; as interesting an album this is.
Got Testament's greatest hits, said "Man their old stuff's great but it sounds like CRAP!" Enter First Strike Still Deadly. EVERY SONG is given a punishing 21st century facelift and Chuck Billy sounds better than ever. Still despise Skolnick's lead tone (he's a great player though) but everything else rocks so hard I overlook it!
