When Steve Hackett left Genesis in 1977, following the Wind Wuthering tour, the band’s “classic era” officially perished. Breaking up altogether would have made sense — prog-rock was hopefully out of fashion this late in the decade, and losing Hackett’s ethereal guitar work was a massive blow. But this was familiar territory for Genesis, who’d already weathered the loss of founding members Phillips and Gabriel. So they used the trio formation as an excuse to re-tool their musical chemistry on 1978’s …And Then There Were Three: reining in the extended solos and complicated song structures, weaving in more pop-friendly choruses. The trio hadn’t abandoned prog altogether, as evidenced by the rhythmic gymnastics of “Down And Out” and the jazzy mysticism of “The Lady Lies.” But the album’s best song is a complete deviation: “Follow You, Follow Me,” their first Top 40 US single, finds Collins belting about life-long love over a dreamy soft-rock groove. It ain’t “Invisible Touch,” but it opened the door for it.
