Ry Cooder and Joaquim Cooder have more in common than just sharing a last name and being father and son. They also both have new records out: Guitar- and singer-songwriter legend Ry’s is the album “The Prodigal Son.” Following in his musical footsteps, percussionist and singer-songwriter Joaquim’s is the EP “Fuchsia Machu Picchu.” They’re also both on the bill – in two separate sets – at the Wilbur in Boston on June 7.
