El Canto del Loco (The Song of the Madman) are unbeatable when it comes to the spunky, high-energy pop-rock they play so well. The Madrid-based group's seemingly effortless sound overflows with youthful exuberance even when they go acoustic. Fronted by the charismatic Dani Martín, they deliver engaging lyrics, hook-filled melodies and a lovable overall vibe.
