Never heard of these bands before so I checked them out on youtube. Avenger - "The Slaughter Never Stops" Is the one that I liked best. Good recording too!
Quartz and Avenger are NWOBHM bands. I found the newer releases I owed me, specially "Against All Odds" from 1983, metal the way it should be. The new Avenger is not as solid, but I like these old bands returns. I'm searching for the new Tytan now, came this year but too expensive.
Crucified Barbara is a now defunct all female Swedish band. I got two of their releases and I found their second album "Til' Death Do Us Party" cheap finally.
Vulcain is a classic 80's French band, the "French Motorhead" as dubbed once. Have been tracking their material for years to no avail, and finally found their debut (remaster) at a great price. Love the French metal bands from the 80's : Sortilege, H-Bomb, High Power, Blaspheme, Killers, ADX, Attentat Rock, Vulcain, specially since they sing in French.
Viikate is a weird combination I admit it. But I had that album as MP3s for years, and finally found it in physical format. Sounds very nice in Finnish, may get more material from them eventually.
