Following that up with the first quartet of Othmar Schoeck (1883-1957), a substantial late-Romantic work that nonetheless has a lot of almost neoclassical-ish touches (Martinu neoclassical, not Saint-Saëns neoclassical). Pre-echoes rather since I think this piece is from the 1910s. I'm finding it a compelling piece, if a bit rambly and directionless in places. It's also rather enjoyable to follow along with the score on IMSLP.

The melodies, harmonies and developmental twists are delightful, however, though the idiom wears thin after a while.
