I want to know the answer to the following question:
What concept is characterized by abrasive leads and darker arpeggios?
All the background I'm provided with is that "The growing popularity of such artists led to the emergence of electro house and progressive house blended sounds in popular music, such as singles Lady Gaga's "Marry the Night", The Black Eyed Peas' "". Is that enough to answer the question?
Answer: no
