Here is one of the truly great Walt Disney cartoons, The Band Concert from 1935. This film short was ranked #3 in Jerry Beck's list of "The 50 Greatest Cartoons," just behind What's Opera, Doc? and Duck Amuck. This was Disney's first Technicolor cartoon released to the public, and it just looks wonderful.
Mickey Mouse has been a soulless corporate logo for so long, it's almost impossible to remember that he was one a real cartoon character, and a good one at that. I always preferred Donald Duck, but the two made a great pair, and this is really the golden age of Disney cartoons, just before Snow White and the Seven Dwarfs ushered in a new era of feature animation.
The storm sequence in The Band Concert does remind me of the opening sequence from Isao Takahata's Gauche the Cellist. That was a surprise to me, since Takahata does take any influence from Disney (Hayao Miyazaki is a great fan of Dave Fleischer, which is as close as they get). But this speaks to the influence and stature that this cartoon commands, the world's first Technicolor animation released to the public. And Walt Disney was a pioneer in the use of sound, as this video demonstrates.
Anyway, enjoy The Band Concert. And go play outside today, it's Saturday!
