She'll be back in the AB on 2 October for something especially groovy: her ongoing project Planet Janis, a tribute to the influence of Janis Joplin, coupled with a tribute to Jimi Hendrix.

Joplin, also born in Texas, died on 4 October, 1970, almost exactly 40 years ago to the day. The 40th anniversary of Hendrix's death was just last week, on 18 September.

The Planet Janis show is now in its sixth year. "I discovered her when I was young, and she encouraged me to be myself," says Scott (pictured above). Nobody, not even the blues legends by whom she was so heavily influenced, sang like Joplin. "Her voice sounded really strange at the time. It's still not my favourite voice among singers, but she's one of my favourites for personality."

Joplin's life was cut short by drugs and booze: she died of an overdose when she was only 27. Her voice had an incomparable edge, and a youth spent as a social outcast (despite a churchy, middle-class upbringing) gave her insight into the isolation and alienation contained in the blues.

Like Joplin, Scott started off singing in church. "I also had kind of an unusual voice, but not in that raucous way," she says. "I sang alto from when I was very young." Since then, she's inhabited the world of blues-rock, a much-maligned genre thanks to too many bad pub bands.

Scott doesn't sound like Joplin, but that's OK because Joplin's voice and style are so particular that a little goes a long way. Scott, meanwhile, better fits the company of someone like Bonnie Raitt, with a voice that speaks of too much bourbon and too many no-good guys. She's seen it all and sings in sad resignation rather than a shout of pain.

"I was attracted to Janis because I wanted to show a different aspect of her - how she worked hard, how she was educated, her influences and what made her what she was - another side of her than just the whiskey bottle and the bad-ass attitude."

Scott won't be alone onstage: French blues guitarist Paul Personne and Antwerp's alt-rock duo Black Box Revelation are there to pay their respects to the legends of 1960s rock and roll, as well.
