If you’re going to assemble a series of recordings that pay tribute to the pioneers of bluegrass music, then you’ll want to start with Bill Monroe and The Blue Grass Boys. And that is exactly what The Infamous Stringdusters did in 2021, releasing a loving collection of tunes associated with the “Father of Bluegrass.” The quintet followed that last year with an album of their own songs, Toward the Fray, but now they’ve returned with another homage. And once again, they’ve gotten it right. After you’ve honored Bill Monroe, Lester Flatt and Earl Scruggs have to come next, and the Stringdusters have done the duo proud with this second set of covers. The new collection, like its predecessor, is an EP, which means you’re getting six tracks, 20 minutes of music in all, maybe enough to squeeze in during a quick lunch break. For the all-too-brief tribute, the group opts for a mixture of semi-obscure tunes and a few more familiar ones, including the lone instrumental, “Earl’s Breakdown,” which gives not only banjoist Chris Pandolfi a chance to shine, but the others—Andy Hall (Dobro), Andy Falco (guitar), Jeremy Garrett (fiddle) and Travis Book (bass)—as well. Among the other five tracks, the opening “I’d Rather Be Alone,” originally cut by Flatt and Scruggs in 1954, and “Cabin on the Hill,” which showcases the group’s shimmering vocal harmonies, are highlights, but you can take your pick, really—there isn’t a false note to be found.
