Violin concertos/Symphonies....

This is a must have:
"Stravaganza: Violin Concerti Op 4 1-12" Antonio Vivaldi (Composer), Arte dei Suonatori (Orchestra), Rachel Podger (Performer)

Furtwangler - Beethoven's 9th on EMI (1951), Music and Arts (wartime) Tahra (Lucerne festival - last performance) The EMI from '51 has the best sound - in mono. Also Von Karajan Beethoven's 3rd from the 1961 cycle but not from the later cycle's. Jochum's Bruckner cycle either on EMI or DG - very similar - also Wand's Bruckner 4 on RCA.

Eugen Jochum's Bruckner 9th with the Staatskapella Dresden. His Bruckner 1st with the same orchestra is also mighty good. Also try Jochum's Bruckner Te Deum with the Berlin Philharmonic.

Try the 4th movement of Shostakovich's Symphony No.12: "step by ponderous step, the inexorable carapace of proletarian praxis rides athwart the imperial walker of historical inevitability."
