Richard Lyons - Understanding Digital Signal Processing
Focuses more on explaining the concepts behind the math than presenting a wall of theorems. Given that math is the language of DSP though, there's still a reasonable amount of math.
It assumes the reader has an EE or similar background, but I think it's still fairly approachable regardless. Given that my own background is in EE/embedded systems though, I'm not sure what my opinion counts for there.
