A post-punk collective based in Athens, Ga., the New Sound of Numbers have cobbled together an intriguing sophomore album in “Invisible Magnetic.” Spearheaded by Hannah Jones and featuring members of Pylon and Olivia Tremor Control, the New Sound of Numbers is relentlessly upbeat on the 14 track release. The opening salvo of the title track and “Complete” are fantastic as are “Energy Plan” and “Feel” which offsets some of the more out-there experimentation that crops up from time to time. This one’s worthy of a few spins.
