An easy way to experience lots of quality classical music by a single composer is Christ Church Cathedral's spring music festival. This year, it's all about Johann Sebastian Bach. BachFest 2008 takes place April 25-27 at the Cathedral, 125 Monument Circle. The opening show features organist David Schrader at 7:30 p.m. Friday, April 25. Bach's famous B Minor Mass will start at 4:30 p.m. Sunday, April 27, featuring a baroque choir and orchestra plus vocal soloists Suna Avci, Kathleen Hacker, Steven Rickards, Mark Mowry and Stanley Irwin. Technically, both concerts are free, but there's a $10 suggested donation. For more details, call (317) 636-4577.
