Plant was spotted having dinner at Monday evening at David Burke's Primehouse at the James Hotel, followed by an appearance in the hotel lobby bar, where he performed an impromptu jam for the crowd.
And last night, Plant joined Los Lobos for a song during the band’s appearance at The Taste Of Chicago festival; they played the R&B classic, “Treat Her Right.”
A fan report from the show suggests Los Lobos told the Chicago crowd that they had shot a video with Robert earlier in the day; Plant is covering the Los Lobos track “Angel Dance” on his new album, Band Of Joy, due in September. Here's my post about the album.
The video here is fan-shot, so heads up: it starts very shaky but evens out for the bulk of the song.
