Before it’s time to pack up those summer whites, enjoy the fine arts along with some fine weather this weekend.

Saturday and Sunday: FringeAL FRESCO
East Fourth Street between Bowery and Second Avenue, 1 p.m. to 5 p.m.
The Fringe Fest comes to a close this weekend, but not before two more days of free outdoor entertainment on Fourth Arts Block. At 1 p.m. each day, watch “Jack and the Corporate Beanstalk,” an interactive play by the Occupy Wall Street Puppetry Guild. The free theater goes into the evening, with the block’s restaurants pulling their tables into the street for al fresco dining.

Saturday and Sunday: “Jason and the Argonauts: Tales from the Argonautica”
East River Park Bandshell, between Cherry and Jackson Streets, 8 p.m. to 10 p.m.
This adaptation of the “Argonautica,” the Greek epic poem in which protagonist Jason searches for the “Golden Fleece” and falls in love with the sorceress Medea, will likely be a trip. The Faux-Real Theater Company promises “bouzoukis (Greek guitars), drummers, platform shoes, and a chariot full of masks and flashy costumes far from the white togas we’ve come to expect from ‘the classics’ of the past.”

Sunday: Charlie Parker Jazz Festival
Tompkins Square Park, 3 p.m. to 7 p.m.
Irene drove this annual event away from Tompkins Square Park last year, but it’s back for its 20th installment. Once again, jazz masters will perform a stone’s throw from Bird’s old house on Avenue B. This year: Grammy nominated vocalist Gregory Portner, tenor saxophonist Patience Higgins and his Sugar Hill Quartet, genre benders Dapp Theory, and pianist Sullivan Fortner.
