also the Apress "Beginning Haskell" looks pretty good, tho the writing isn't perfectly clear. The example topics and sample code look good, and that's what mostly counts.
The books by Hutton and Simon Thompson ("Craft of FP" 3rd ed)are good intros as well. Haskell school of music is really good, but not sure for people who aren't versed in music topics (harmony/theory, composition, MIDI, DSP.
Here is the list of materials I used to learn Haskell:
1. LYAH, http://learnyouahaskell.com/
2. Real world Haskell: http://book.realworldhaskell.org/read/
3. Programming in Haskell: http://www.amazon.com/Programming-Haskell-Graham-Hutton/dp/0... (No one suggests this book, but I do think this book is well-written and concise.)
4. Video tutorial by Erik Meijer based on Programming in Haskell: http://channel9.msdn.com/Series/C9-Lectures-Erik-Meijer-Func...
5. Advanced topics: http://www.haskellforall.com/2014/03/introductions-to-advanc...
