This Barcelona act makes bubblegum pop to transport listeners to a world of sunshine. Led by Guille Milkyway—the band's singer and composer, who performs alongside five virtual bandmates—La Casa Azul formed in 1997 with a sound that merges '60s pop and disco. Their back catalogue overflows with Europop classics, such as the joyous "Como un fan", which is laden with tinkering keys and purring horns. With its handclaps and emotive strings, the undeniably catchy "Galletas" is all you need to replace a sour mood with a happy disposition.
