The Jon Spencer Blues Explosion won't be part of the main-stage lineup for this

summer's Lollapalooza tour.

A source at the band's label, Matador, told ATN, "it looks like they won't be on

Lollapalooza, although the contract has not formally been broken." Otherwise, the

label had no comment on the unexpected change in plans for the

distorto-blues/punk band, who played a scorching set at last weekend's Tibetan

Freedom concert, other than to say "they were ready to do it."

Lisa Vega, of Scoop Marketing, the company handling PR for the festival, told ATN

that there was "nothing to say" about Spencer's sudden non-involvement. A

replacement act has yet to be named, and Vega could not confirm whether one would

be forthcoming.

ATN previously reported that with the growing number of big-name-act tours

crossing the country this summer, Lollapalooza faces stiffer-than-ever

competition for ticket sales. At that time of the report, representatives for the

tour expressed concerns with keeping Lollapalooza (which a few years ago had a

virtual monopoly on concert-goers each summer) alive and kickin'.

The rest of the line-up for the festival, which begins on June 25 in West Palm

Beach, Fla., at the Coral Sky Pavilion is: Tool, Tricky, Korn, Snoop Doggy Dogg,

Prodigy, Julian and Damien Marley, and Orbital.
