Phish continued their three-night run at Chicago’s Northerly Island with a Saturday night show highlighted by one of the longest versions of “Simple” in the band’s career.

The 27-minute jam anchored the second set as the band showcased some of their very best improvisation since their return in 2009. According to YEMBlog, the performance ranks as the third longest take on “Simple” in the band’s career.

Elsewhere on the night, the first set included many of Phish’s popular opening songs. While the first set didn’t feature the same improv as the previous night, the quartet did offer tight versions of “Stealing Time from the Faulty Plan,” “The Moma Dance” and “The Wedge” early on.

Page McConnell led the band through his own “Halfway to the Moon” while Mike Gordon took the lead on “Ya Mar” before the Chilling Thrilling fan favorite “Martian Monster” and Joy bonus track “Party Time.” The set concluded with “Wingsuit,” “Bouncing Around the Room” and Big Boat‘s “More.”

Before the landmark “Simple,” Phish kicked off the second set with the first version of Trey Anastasio’s Traveler song “Corona,” marking another Anastasio song played on this run as “Everything’s Right” made its Phish debut on opening night.

The second set (and show) belonged to the “Simple” as the group cooled down from the jam with a delicate “Winterqueen” and a brief “Light” whose improv was replaced by a foray into “Scents and Subtle Sounds.” An upbeat “Cities” and euphoric “Slave to the Traffic Light” concluded the strong set before the band returned for a “Loving Cup” finale.

Phish returns to Chicago tonight.
