The classical music season is in full swing, and that means you’ll have to make choices again this weekend. Here are some notable alternatives:

Saturday. Choose between the Minnesota Orchestra’s important “Future Classics” concert of new works by young composers and the Minnesota Chorale’s annual “Bridges” concert, which features a vocal collaboration with the Minneapolis Youth Chorus.

Either way you’re going to hear new music.

The Bridges concert features the first performance of a work by Minnesota’s own Stephen Paulus, titled “Wake Up in the Morning,” plus a song created by Youth Chorus members during an August workshop. The title of that work is perky: “The Music Moves Like We Do.” Saturday’s concert is titled “Sing With Me,” in recognition of a mentoring relationship that has developed between Minnesota Chorale members and the Minneapolis Youth Chorus. It’s billed as “family friendly.”

“Sing With Me” takes place at 7 p.m. at St. Olaf Catholic Church. Go here for information and here for tickets.

The Minnesota Orchestra’s Future Classics concert is the culmination of the annual Composer Institute sponsored by the St. Paul-based American Composers Forum and the American Music Center. For the past nine years, the two sponsors and the orchestra have collaborated to bring young professional composers to the Twin Cities for six days of seminars, tutoring sessions and other events.

Eighty-six composers have taken part in the program and its predecessor, called “Perfect Pitch,” that was first launched back in 1995. Seven composers are participating this year and each will have something performed — either as a premiere or as major first performance.

The “Future Classics” concert is 8 p.m. at Orchestra Hall. Here are the details. 

Sunday: Choices include two afternoon concerts, both at 4 p.m. The Oratorio Society of Minnesota opens its 30^th season with a performance of the beloved Mozart Requiem, and the Metropolitan Symphony Orchestra is headlining Osmo Vänskä as both a composer and a clarinet soloist.

The Oratorio Society’s concert features a collaboration with the Armstrong High School Chamber Singers, which will surely add a youthful timbre to the Requiem. Soloists are soprano Linh Kauffman, mezzo Adriana Zabale, tenor John DeHaan, and bass Seth Keeton. Matthew Mehaffey conducts the chorus, orchestra and soloists. Organist is Helen Jensen. The Oratorio Society performance takes place at Wayzata Community Church. For details, directions and tickets, go here.

In 2008, the Metropolitan Symphony commissioned and performed Vänskä’s “The Bridge,” a work inspired by the collapse of the I-35W bridge in Minneapolis the previous summer. That work is being brought back for a second performance and Vänskä also is appearing as soloist in Mozart’s Clarinet Concerto.

The concert also includes music celebrating major anniversaries in the lives of four musicians — including MSO Music Director William Schrickel, who is marking his 10^th season with the orchestra. In recognition, the orchestra commissioned Illinois composer Stephen Heineman, who is one of Schrickel’s boyhood friends, to write a new work, titled “Metropassacaglia.” Other anniversary observations on the program include “Mutations From Bach” by Samuel Barber (born 100 years ago), the overture to “World on the Moon” by Josef Haydn (died 200 years ago) and the Symphony No. 1 by Felix Mendelssohn (born 200 years ago).

The Metropolitan Symphony performance is at Central Lutheran Church in Minneapolis. The performance is free and no reservations are required. Go here for information.

So get out there.
