Sonic Youth delivered a late shock in 2011 when co-founders Thurston Moore and Kim Gordon split up after 27 years of marriage. The band's future remains uncertain, but in the meantime the group's other core members, guitarist Lee Ranaldo (below) and drummer Steve Shelley, are busying themselves with various side projects. In March, Ranaldo will release a solo album, Between the Times & the Tides, and last week he unveiled the first track from the record. The mid-tempo, guitar churning "Off the Wall" is available at ind.pn/ylLKDo. Meanwhile, Shelley has been drumming up noise with Chicago rock band Disappears. "Replicate", the first track of droning garage rock from their upcoming LP, Pre Language, is at ind.pn/zcAL1Y.
