Hawkwind Brew

[SickthingsUK]

Apologies if I missed this, but what is this? Apparently released last week.

Something new? or just yet another rehash pretending to be something I need. 
I suspect the later obviously, but if so anyone know where these tracks were 
released originally it would be useful.
