Forget J. S. Bach: Philip Glass is the new granddaddy of music…or so sayeth eighth blackbird in its latest album, Filament.

This new release from the Chicago-based contemporary music supergroup cleverly connects the groundbreaking repetitive structures in Glass’s music with American folk tunes, contemporary compositions, and poppy vocals. The album’s name is meant to conjure a mental image of musical threads linking all its performances, new and old.

In this case, “old” is a relative term. The nexus of Filament is “Two Pages,” written by Philip Glass in 1968. It’s a classic illustration of Glass’s signature repetition, a mind-bending 16 minutes of subtly changing patterns. The piece famously sounds meditative and nightmarish at the same time. It’s notoriously difficult for performers–the liner notes compare it to walking a tightrope “with no net below”–but the expert musicians here meet the challenge admirably, almost making it sound easy. Performing this piece alongside the sextet are organist Nico Muhly and guitarist Bryce Dessner (of The National), and it’s no coincidence that both of them are also featured composers on Filament.

In fact, the album opens with Dessner’s multi-movement piece Murder Ballades, inspired by folk songs about real and imagined killings that were passed down through many generations. The murder ballad tradition began in Europe, but Dessner’s piece focuses on the maudlin stories that originally come from early settlers in New England and Appalachia. Dessner chose to arrange three real ballads, “Omie Wise,” “Young Emily,” and “Pretty Polly,” all of which tell stories of love affairs turned violent. Imagine if someone took the music from a Ken Burns documentary and gave it a little edge, and you’ll have an idea of what these movements sound like. The other four ballads in the piece are Dessner’s original compositions, still clearly inspired by early Americana but more deconstructed and intense. In these four movements, Philip Glass’s repetitive, meditative influence is clearly felt.

Nico Muhly’s piece, Doublespeak, is so closely linked with Two Pages that it’s as if Muhly managed to burrow directly into Philip Glass’s midcentury brain. Muhly wrote this piece for the composer’s 75th birthday celebration, so it’s fitting that he chose to salute a decade when “classical music perfected obsessive repetition,” as he puts it. You’ll hear snippets of 1970s staples like In C and Violin Phase flit in and out as the piece alternates between a fast-tempo frenzy and a slow, dreamy state.

As if there weren’t already enough threads connecting these three pieces, eighth blackbird rounds out Filament with a pair of works by Son Lux. The legendary pop-classical electronic composer took sound bites from the album and mixed in Glass-inspired vocals by Shara Worden, aka My Brightest Diamond. The result is a half-ambient, half-catchy five minutes that nicely break up the album’s studied repetition, which can be a little mentally taxing.

It goes without saying that the performance quality on this disc is top-notch, no less fine than any of eighth blackbird’s past albums. You’re luxuriously free to focus solely on the compositions themselves, all of which are worth contemplating at length. In an age when most albums’ connecting filaments are somewhere between ultrathin and nonexistent, it’s a pleasure to listen to a set of pieces with such close ties.
