This is some serious nasty orchestrated cello playing. I mean that as a sincere compliment, this could easily fit in with good metal and hardcore, Two Ton Boa, etc. Ms. Chesley has a master's in cello performance from Northwestern and has been recording for over a decade with other artists, for some time as a band named Verbow, she's also played in recording sessions for Bob Mould. This is excellent music. I recommend all of it. Really. But if you must know, I like 4,5,7 seriously though read the descriptions and pick one.

1 noisy and orchestrated
2 more sparse, pensive
3 noisy and orchestrated, climactic elements
4 romantic sounding somehow
5 beginning has that sort of Christina Carter ambience, but only a bit faster, it breaks out into something nice and intellectual, great
6 something elemental, makes me think of (Arvo) Part in his sort of tintinabulation
7 nice and pretty, moment of repose, woman shouting in the background, Current 93?
8 noisy 'rock' (?!), Two Ton Boa
9 tick tock, breaks out
10 very noisy and dramatic
11 low end noise rumble, long fade out, gets very soft at end.
