The Tokyo City Philharmonic Orchestra (東京シティ・フィルハーモニック管弦楽団) under Taijiro Iimori (飯守泰次郎):
Yes, I know, Holst, which I'm sure marks me out as popular music-loving philistine, but one can't help but be impressed by the excellent and, for once, extremely visible precision of the orchestra in this piece. It is like watching a complicated military drill, or an aerobatic display team being put through its paces.
For those of more studied taste, here's the same orchestra under a different conductor playing a sparkling rendition of the 3rd movement of Prokofiev's Piano Concerto No. 3 in C major.
