The Kitchener Blues Festival was great, despite the rainy weather. Within a few hours, I heard Ronnie Hawkins & the Hawks (chaotic, with three guitarists and two keyboardists), Maria Muldaur (largely “swampy” Louisiana country/gospel-y blues), Leon Redbone (mostly olde-timey songs, along with a pianist), and Elvin Bishop (excellent band, including lead vocals by most of them).
