Raymond Scott Quintette - Powerhouse - Hit Parade

@ the 1:25 mark the composition changes and you would have sworn until now that this was two different pieces.

Though this is purely acoustic apparently Raymond Scott was also a pioneer in computer graphics (did title sequences for Vertigo one of Hitchcock movies) as well as very early synth design and synth music exploration.
