Here are two albums, released on the same label, that use jazz influences very heavily. What I found most interesting about contrasting the two, is that Unconscious Collective use improvisation heavily, and tend towards the shapeless side of jazz, while Sans Soleil rely heavily on melodic leads with a bit more of a subtle jazz-tinge. Really interesting stuff, and my preferred of the two would be Sans Soleil
Mausoleum Gate's self-titled album ("Mausoleum Gate") is a nice vintage-sounding (late 70's/early 80's) traditional metal band with a slightly campy Satanic theme (think Hell). Musically it's catchy, well-written and even somewhat humorous - the giggling at the beginning and the random Deep Purple-styled outro stood out especially.
Liblikas - Mothers' Finest, an EP released in late 2014. It's stoner/sludge/psychedelic metal. I'm not too familiar with that kind of stuff, hence the ambiguous description, but I found it to be quite enjoyable.
