Seems like the other Forum regulars here have blogs, so rather than be an outlier, I figured I’d go ahead and start one.

I’m currently practicing a student Concertino I like, to work on (among other things) my bowing.  Violin Concertino in the Russian Style, Op 35, by Aleksey Yanshinov (or Janschinow, depending where you look).  I don’t think it is done often by students in the US; I found it on some lists in Europe, though. 

I’ve found a couple of folks who recorded their playing of it on YouTube that I’ve posted below.  I prefer the ramikable version: I think it is more expressive, or at least it is closer to what I hear in my head when I’m practicing it.  

I’m currently working on the 3^rd movement, working on speeding it up (at around 05:39 on ramikable version). ramikable plays it faster than Twiolins, which I like better--or at least, I like the sound of it better; I would probably "like" to just meander along

ramikable version:

The Twiolins version:
