Jazz guitarist Stanley Jordan sat in with Dave Matthews Band at East Troy, WI’s Alpine Valley Music Theater this weekend. The Chicago-bred musician joined DMB on both Friday and Saturday. On Friday night, Jordan emerged for “Proudest Monkey” and remained onstage for “Satellite.” Then on Saturday night, Jordan sat in on both “Rhyme & Reason” and “The Dreaming Tree” during the main portion of Dave Matthews Band’s set. He returned at the end of the show to play Dave Matthews’ guitar while the frontman danced at the end of Sly Stone’s “Thank You (Falettinme Be Mice Elf Agin).” Adding to the festive show closer, DMB horn players Jeff Coffin and Rashawn Ross squirted the crowd with water guns during the tune. It was one of the longest shows Dave Matthews Band has ever played.

Jordan already sat in with Dave Matthews Band during three shows in late May (two in Hartford, CT and one in Scranton, PA). He performed with Umphrey’s McGee earlier in the week and will join the group in New York later this summer. His busy summer also includes a series of Rambles with Phil Lesh later this month.

In other news, on Friday night bassist Stefan Lessard honored Independence Day by riffing on “The Star-Spangled Banner” during his intro to “All Along the Watchtower” and the band busted out the rarity “Blue Water.” Matthews also surprised the crowd when he joined opener Brandi Carlile for a cover of “Angel from Montgomery” during her set last night.

Dave Matthews Band’s summer tour continues at Clarkston, MI’s DTE Energy Music Theatre on Tuesday.
