If you have a decent grasp of sight reading skills and want a crash course in neoclassical shred, it's a great piece to learn. The piece is called 'Winter' from the 'Four Seasons' Opus. It's also the darkest of the 4 pieces. I've made it up to measure 30 so far, and loving it!
I have the Schirmer transcription of it. Schirmer makes the best classical transcriptions!
Almost every scale and mode is altered to some extent, which makes pattern playing chalenging, as you have to memorize different patterns for each run. It also features some really strange double stops (F and Gb double stop, anyone?).
Anyway, it's a fun piece, and an advanced guitarist can probably get the first movement down in a few evenings.
