“Occasional Music for Early Winds and Plucked Strings,” a free concert by William Feasley and Sarah Weiner, will take place at the Montauk Library Saturday evening at 7:30.
Mr. Feasley, the first guitarist to be awarded the Peabody Conservatory’s Artist Diploma, will play the theorbo, a long-necked string instrument, and a 19th-century guitar, in addition to the classical guitar. Ms. Weiner, who has performed both modern and classical music with ensembles around the country, will play baroque oboe and recorder.
