La Casa Azul is a Spanish musical project led by Guille Milkyway, known for its fresh, melodic pop sound full of electronic and retro influences. Since the late '90s, La Casa Azul has created indie pop anthems like “La revolución sexual,” “Tu mejor amigo,” and “Nunca nadie pudo volar,” combining '80s synthesizers, nostalgic lyrics, and a very personal style. Their music stands out for its ability to evoke feelings of youth, love, and melancholy, establishing itself as one of the benchmarks of contemporary Spanish alternative pop.
