Did you know that Art Garfunkel (pictured) taught Paul Simon how to sing? Garfunkel’s liable to mention that when he hits City Winery for intimate Friday and Saturday shows, exactly five weeks before Simon stops at the larger TD Garden down the block on his self-proclaimed farewell tour. Yeah, it looks more unlikely than ever that the estranged duo will reunite again before retirement. But the good news is that they’re each in town this spring and Garfunkel’s voice is near-fully restored since his gradual recovery from a vocal cord injury that scuttled a Simon & Garfunkel reunion in 2010. Or if you want a somewhat similar Friday alternative, you can head to the Center for the Arts in Natick, where Joan Osborne sings the songs of Bob Dylan.

Saturday percolates with a few concert options, including Providence’s haunting folk-rockers the Low Anthem at Brighton Music Hall, the rising alt-R&B duo Marian Hill and veteran R&B-soul hitmakers Tavares, sharing a bill with the Stylistics at Lynn Auditorium. But Saturday’s best catch, particularly if you want to dance to lively Afro-Cuban rhythms, might be the Grammy-nominated Pedrito Martinez Group, back at the Sinclair in a concert presented in association with World Music/CRASHarts.

Somerville’s Porchfest was moved to Sunday to avoid Saturday’s rainy weather, providing an opportunity to stroll the streets of that city and catch free music in a wide range of styles under the sponsorship of the Somerville Arts Council. Among the performers will be Harvard-born singer Ashley Jordan (from noon to 2 p.m. at 43 Chester St.), winner of last year’s Boston Music Award for country artist among her many regional awards. And here’s a map with a list of Porchfest performers and times.

Sunday’s actually the busiest day of the weekend – and not because everything jives with Mother’s Day. That’s the case with grungy sludge-metal pioneers the Melvins, surfacing at the Paradise Rock Club (though I guess it depends on the mother at hand). Other options include Texas’ roots-rocking Shakey Graves at Royale, folky Baltimore indie-rockers Wye Oak at the Sinclair, singer/songwriter Richard Shindell at City Winery and eclectic Louisiana indie-pop group Givers at Great Scott.
