Hmm, let's see... there hasn't been anything too recent that I've come across lately that's really captured my attention, besides a couple of arranges. I've been shifting between three different yotube uploaders, so there is still a lot I haven't checked out yet.

As for kinda recent, WAVE's Symphonic Caprice "Evening Primrose" album, which an arrangement of the StB soundtrack, is pretty good. TAM got together with 3L and did a very beautiful song called 追憶のソール. Some circle called Tatami Stugiwo arranged a medley of the IN soundtrack called The Symphony of the Imperishable Night that was pretty cool. Virus Key is also a pretty good circle, and they have really good arranges of Phantom Ensemble, Luna Dial, and a lot of others.
This one is a tiny bit old, but it still blows me away every time I listen to it. It's an arrangement of Byakuren's stage theme and her boss theme.
