How many radio hosts can do a “Wozzeck” warm-up show and then turn around and introduce an evening of jazz favorites? Well, this one will do his best.

Join me this afternoon — and this evening — on WRTI, as I fill in for Mark Pinto and Jeff Duperon. I’ll be on at noon with some music of Bach and Barber. Alban Berg’s “Wozzeck” is coming up at 1:00, from the Lyric of Opera of Chicago. In between, it will be the opera preview.

New releases, hosted by yours truly, will follow at 3:00. Then it’s “Discoveries from the Fleisher Collection” with Kile Smith and Jack Moore at 5:00. The focus this week will be on music by American composer Edward MacDowell.

Jazz begins at 6. Somewhere along the way, I’ll grab some tea and a sandwich. Listen today, in Philadelphia at 90.1 FM. You’ll find a full list of frequencies at wrti.org.
