Good morning, blueologists, and welcome to another Tuesday Bluesday. We open with five hours of bluesy women, then it’s John Mayall live from the UK, and an interlude of swamp blues with a Marcia Ball ‘Spotlight.’

Here’s your Tuesday Bluesday lineup:

9:00 a.m. Ladies Sing The Blues: Various Artists

We start off with the ladies, some of them blues legends, some those who simply respected the blues and kept the genre fresh and current. You’ll hear Billie Holiday, Big Mama Thornton, Ruth Brown, Nina Simone, Janis Joplin, Koko Taylor, Bonnie Raitt, Christine McVie, Marcia Ball, Ellen McIlwaine, Susan Tedeschi, Irma Thomas, Tracy Nelson, Etta James, Linda Ronstadt, Sippie Wallace, Bessie Smith, Shawn Murphy, Angela Strehli, Aretha Franklin, The Blues Broads, and more!

4:00 p.m. John Mayall Live at Leicester Square Theatre, London, UK, November 1, 2010

A true blues master visits us this afternoon, live from Leicester Square Theatre.

8:00 p.m. In The Spotlight: The Music of Marcia Ball

Marcia Ball is simply teriffic, an award-winning blues singer, songwriter and superb pianist whose music was described by The Boston Globe as “an irresistible celebratory blend of rollicking, two-fisted New Orleans piano, Louisiana swamp rock and smoldering Texas blues from a contemporary storyteller.” You’ll enjoy her ‘Spotlight’ feature.

We start and end the day with the ladies today, and that is always a good thing. We’re on 24/7 without commercial interruption, and with no chatty DJs to spoil the flow. The button is, as always, below!
