Head out to the parks this weekend for a pair of free concerts.

• On Saturday, the volunteer Arizona Symphonic Winds perform at Udall Park, 7200 E. Tanque Verde Road, at 7 p.m. Admission is free.

• On Sunday, the Tucson Pops Orchestra, comprised mostly of moonlighting Tucson Symphony Orchestra musicians, host guests Sons of Orpheus and vocalist Lindsey McHugh. That concert begins at 7 p.m. 

Admission to either is free.

Conductor László Veres leads both ensembles. The Winds perform Saturday nights through June 8; the Pops play Sunday nights through June 9.
