"[7] In the studio, Jones and Armstrong were joined by bassist Tim Luntzel and drummer Dan Rieser.
[8] Stephen Thomas Erlewine of AllMusic gave the album three and a half stars out of five, saying "Their approach is not dissimilar to that of Don and Phil in 1958; the brothers didn't scrupulously re-create the sound of the past, they sang the songs in a way that was true to them, which is precisely what Billie Joe and Norah do here.
Jones' suppleness sands down Armstrong's ragged voice, he gives her grit while she lends him grace, and these qualities are evident throughout this lovely little gem of an album.
It might seem initially unlikely that Armstrong and Jones have as much rootsy connection to the music (and to the state of Kentucky) that Don and Phil Everly do, yet after listening to Foreverly, it's not hard to believe that maybe somewhere deep down they could.
"[11] Phil Mongredien of The Observer gave the album three out of five stars, saying "While hardly a move into brave new musical pastures, it's not without charm and the use of a female voice puts just enough distance between this and the original, the entwining harmonies recalling Gram Parsons's duets with Emmylou Harris.
"[15] Mark Lore of Paste gave the album 7.6 out of 10, saying "No doubt Foreverly will steer a few more listeners to Songs Our Daddy Taught Us.
"[16] Will Hermes of Rolling Stone gave the album three and a half stars out of five, saying "Just when you thought Green Day's Billie Joe Armstrong couldn't commit a worse punk heresy than doing a Broadway musical, boo-yah!
"[17] Robert Ham of Alternative Press gave the album four out of five stars, saying "To add even more praise to the folks behind Foreverly, whomever it was at Reprise that decided to schedule this for a late fall/early winter release deserves some credit as well.
Foreverly feels custom made for long walks through leaf-strewn streets or a brisk dark evening at home.
"[10] Zach Schonfeld of Consequence of Sound gave the album two out of five stars, saying "Mediocre on every count, the resulting set of tracks won't change anyone's mind about any of the artists involved (that's presuming it won't make you like the Everlys less), but as a fleeting curiosity, it's precisely what it says it is — with little imagination to spare.
