As New Mexico celebrates 100 years of being one of those 50 stars on the blue upright, the city is planning the largest party ever held in Albuquerque: Centennial Summerfest is from noon to 9:30 p.m. on a closed-off stretch of Central between Second and 10th Streets. Multiple pavilions (including an authentically constructed 19th century Territorial Village) representing the eras of New Mexico’s history will offer musical entertainment and dancing. Plenty of food, vintage car shows and an arts market reflect the modern. Centennial Summerfest draws to a close at 8 p.m. with a headlining performance by Los Lobos at Civic Plaza. All events are free to the public. For an extensive schedule of events, visit abqsummerfest.com.
