good luck with these 
The first one is Wendy (nee Walter) Carlos' grand opening theme to Stanley Kubrick's brilliant 1971 film adaptation of Anthony Burgess' "A Clockwork Orange" (can you tell I'm a fan?). What the exact title is I can't recall (without popping the DVD in and checking credits).
The 2nd is too short for me to determine. If I know a work, I can almost always place it dead-on, or nearly so, and this didn't happen, so I don't know it.
[Unfortunately, due to severe depression, 13 years ago I underwent 12 treatments of ECT in 4 weeks, which helped my depression, but laid waste to a remarkably well-developed memory which aided (and was aided by) my work as a librarian. In one month, a vast array of knowledge was turned almost to a
tabula rasa, and only some of that memory system has returned - much probably never will...
