When we settled into the studio for this week's All Songs Considered, a clear theme quickly emerged: We had a whole lot of music by artists we already adore! This includes a rare acoustic demo by R.E.M., a glorious new electro-pop cut from Sylvan Esso, a heartbreaking tribute song from Sharon Van Etten and more.This year marks the 25th anniversary of R.E.M.'s 1991 classic album Out Of Time. To mark the occasion, the band is releasing a deluxe version of the album that includes early acoustic demos of every song, including the one Robin Hilton kicks this week's show off with, "Radio Song." Stephen Thompson follows in the same spirit with Sylvan Esso's brand new "Radio," a somewhat retro synth thumper that mixes the band's signature dance pop with singer Amelia Meath's searching, often melancholy vocals.Also on the show: Sharon Van Etten's stirring tribute to the victims of the Pulse nightclub shootings in Orlando, Fla.; English poet, playwright and rapper Kate Tempest and a fabulous kiss-off from the Phoenix, Ariz. band AJJ. Plus, John K. Samson, lead singer for The Weakerthans, returns with a sentimental new song that has Stephen thinking of happier days.
