Billed as a battle of the bands, 93.1 El Rey will host two of Aguililla, Michoacan's most beloved hometown heroes—La Nobleza de Aguililla and La Mar-K de Tierra Caliente. Credited with popularizing music from the tierra caliente region within the US, La Nobleza's veteran sound is a faintly futuristic take on banda, pairing drums and electric guitar with a background of synthesized accordions, strings, and harps. Also hailing from my own grandparents' small town are the match's underdogs, La Mar-K, who have quickly risen in ranks since forming in 2007. As the two go mano a mano at this daytime family affair, get warmed up for the big fight with local acts Ruta Libre and Domador de la Sierra. And if this wasn't already reason enough, a ticket to the show gives you entry to the rest of the Rose Festival for the day. EMILLY PRADO
