I quite enjoy Lick It Up, It makes a nice companion piece to Creatures Of The Night.
Not one of their best albums but I'd call it a solid effort. All Hell’s Breakin’ Loose I think is one of the best singles they ever wrote.
My biggest annoyance with this album is they didn't let Eric Carr sing Young & Wasted.
Disagree with you about Vinnie Vincent being limited, I think it was his guitar playing that gave them a shot in the ass they needed, much like John Sykes in Thin Lizzy around the same time.
And if you want to see Vinnie Vincent was doing before Kiss.......
