Apparently Vyper suffered from the familiar situation of their record label going tits-up and later in the band's life there was two versions of Vyper touring, ala LA Guns, Ratt and so many other hard rock bands in recent years.
In terms of sound, this one bounces between AOR-edged hard rock and NWOBHM-influenced melodic metal. You can definitely hear a Judas Priest influence on the song Dealer, and for the most part the guitar sound is heavier than you would usually hear on AOR/hard rock.
Other songs have a definite Ratt or WASP sound to them, although singer Christy Black doesn't attempt anything close to Stephen Pearcy's or Blackie Lawless's rasp, sticking to straight-forward singing. Some of the lyrics are a bit too simple ("Nighttime is wild so don’t bring your child to the park" as a chorus for example), but this is good, rare stuff - if you like your Sunset Strip glam rock to have a heavier edge to it you'll enjoy this.
