<p>UC Berkeley is top-notch for political science and music history – one of the best in the US by any standard; but it is hard to get in for someone who is not a California resident (and for those who are), it does not offer “music theory” (no major music department west of the Mississippi seems to offer a music theory major, or many courses beyond the 2 year harmony sequence and counterpoint) and performance is not a strength, though there is a good orchestra and good chamber coaches.
There are innumerable schools that would meet your criteria. In the LAC category, Oberlin, Williams, and Wesleyan stand out.</p>
