Recommendations for books on complex analysis and on measure theory? I'm looking for a book on complex analysis that has a similar writing style to either Terry Tao's Analysis II or Nathan Jacobson's Basic Algebra series. I have found both of these extremely easy to read and follow the proofs given quite easily, or at least I have so far. Preferably the level would be for an advanced undergraduate course or a book used in a first year graduate class on complex analysis. 

For the measure theory book, I was wondering what a good book would be for a study of the subject starting from almost the ground level (like why Riemann's criteria for integrability is not entirely sufficient), but would be accessible to an advanced undergraduate.
For complex analysis, I would recommend Marsden and Hoffman's Basic Complex Analysis.  Very detailed and shows every step, and it's a good introduction for those not ready for Rudin (Real and Complex anaylsis).  As for measure theory, baby Rudin (Principles of Mathematical Analysis) is undoubtedly the standard to which all others should be held.  The text starts by proving most of the theorems used in calculus and culminates with great chapters on measure theory and the Lebesgue theory of integration.
For complex analysis I would suggest either Stein's Princeton Lectures on Analysis Volume 2- Complex Analysis or Freitag's Complex Analysis.
As for measure theory there is this great book by Folland: Real Analysis Modern Techniques and Their Applications.
It was the book that I used when I took the course, and I really liked it. I found, especially after Chapter 1, that was a delightful experience to read it, and learn from it.
Hopefully you'll like these books just as I did.
