It sounds like KSPC from Pomona College, which as noted above is apart of The Claremont Colleges.
That station can actually be picked up quite a distance away, albeit with a fuzzy sound.
From what I recall their transmitter is located on ground level there in Claremont, which makes it kind of interesting how far their signal can be heard.
It is the true essence of a college radio station with students playing their record collection and ranting on the air.
