Like the stylistically similar Cut Copy (for whom it opened earlier this month at the House of Blues), as well as past tour mates like Chromeo and such studio bros as LCD Soundsystem, New York City’s Holy Ghost! makes music that dwells in the borderlands. It’s a cracking disco four-piece live, but it’s also a DJ/production duo. Here on record, the bass-funk and stuttering hi-hats snake through the synth haze and plinking keys like a forceful clubber pushing his way through a packed crowd. The balance of the record, some of which appeared on last summer’s brilliantly efficient dance primer “Static on the Wire’’ (its best song “I Will Come Back’’ curiously omitted here), feels like a trip through the picked-over record crates of NYC’s danceable past. Tracks like “Hold On,’’ with its handclaps, dirty bass, and jangly guitars, seem conjured directly from disco decades gone by. “Why do the good things happen in the past?’’ the lyric asks. By the time yacht rock icon Michael McDonald shows up for a breezy croon on “Some Children,’’ that nostalgia fetish feels fully consummated.
