What else has french band Atrox released except "Infest and Desecrate" CDr and the split demo with Malicious Secrets? (and is this split demo still available somewhere?)

Add their first 4 tracks Demotape, Self tittled on Spikekult (SPK009), and I think that's all....

the split demo with malicious secrets on Spikekult actually never came out
both bands had single demos released
(though it was initially meant to be a split release)
the tape version has been xeroxed over & over again here & there by other distributors
& the band did do also cdr versions of it
+ "infest..."
as of now, I think the act is defunct
or seekin a suitable drummer

I talked with their singer about that some weeks ago, she said they're not dead, but things are very slow it seems...

Thanks for the info, hope they will find a drummer...
And I have also heard of an Atrox EP released by Danza Ipnotica, is this another band? (I don't have the EP yet)

most likely the norsk one?!

ok, never heard of them...

Yes it is the norwegian band.
