[3] Greg Kot of the Chicago Tribune stated that the band "finds the sweet spot between tranquillity and propulsion" on this release and that they sound "focused on moving ahead, ever in between stations".

[4] Classic Rock's Julian Marszalek scored In Between 4 out of 5 stars, declaring it a career-best for the musicians whose "grip of melody remains very much in place throughout, as do their love of jangling intertwining guitars and a strict sense of rhythm".

[5] In the Los Angeles Times, Randall Roberts emphasized the continuity between this music and the band's earlier work, stating, "like most of their songs, the new ones are fueled by seemingly simple but absolutely engaging riff-based melodies, which launch from the starting gates like thoroughbreds at the Derby and run with focused power".

[8] At PopMatters, Ed Whitlock gave In Between an 8 out of 10, calling it a testament to "strict adherence to a framework to reveal the deepest levels of creativity and mastery of vision" with the interplay of the band members, with specific praise for each.

[11] Jim DeRogatis of WBEZ-FM praised the "irresistible forward propulsion of the slightly syncopated twist that [percussionist Dave] Weckerman, drummer Stan Demeski, and bassist Brenda Sauter put on their Bo Diddley-via-the Velvet Underground grooves, combined with Bill Million’s relentless rhythm guitar and Glenn Mercer’s harmonic decorations and occasional lead-guitar eruptions" stating that the band's sound is the same as it has been for decades, but that is a good thing and they remain "undiminished, as fresh and undeniable today as they were" in their early career.
