Just a few days after many churches celebrated Easter by listening to the “Halleluia Chorus,” today marks the 250th anniversary of composer George Frideric Handel’s death. Paul Laird, a Kansas University musicology professor, and the period-instrument group Collegium Musicum will mark the occasion with a lecture and concert titled “Beyond Messiah: The Life and Music of George Frideric Handel.” Laird will discuss Handel’s life, compositions and style, and the concert will include two arias from handel’s operas, two concertos and excerpts from “Music for the Royal Fireworks” and “Water Music.” The free lecture/concert is at 7:30 p.m. today at the Hall Center for the Humanities, 900 Sunnyside Ave., KU campus.
