Miscellaneous music news.

Digable Planets has canceled their U.S. tour, which includes their April 17 stop at Crowbar. The trio has broken up again for the same reasons they broke up before — irreconcilable differences. Here's are some key quotes from the all-caps letter the band sent to fans via MySpace (I've de-capped it for your reading convenience): "…The 3 insects from outer space have been infected like every other great group in hip hop history by irreconcilable differences between the principle members ... Mary Ann Viera formerly known as Ladybug has decided at the last minute that she wants to talk away from the group and not honor this tour ... The other two members have no choice but to cancel this tour and regroup ... The group members will go their separate ways but group creator and producer Butterfly along with Doodlebug will continue to collaborate on music and in the near future will announce the introduction of a new music collective that they are putting together … This does not take away from the legacy created by the Digable Planets in 1993 ... but it does bring us to the end of an era ..."

Another sign the economy is in the can: ticket discounts at the big name shows. Amway Arena is offering $35 tickets to Fleetwood Mac's April 20, and Ford Amphitheatre is offering a special weekend sale for the April 26 Nickelback concert ($25 reserved, $15 lawn if purchased between 10 a.m. April 3 to 10 p.m. April 5). Both are Live Nation venues. I think we're going to start to see alot more of this as the months progress and sales get slower and slower.

Willie Nelson has re-scheduled his show at Ruth Eckerd Hall; he'll be stopping in Clearwater October 20. Tickets for the originally scheduled date (Tuesday, March 17) will be honored.

Lollapalooza, which takes place Aug. 7-9 in Chicago's Grant Park, kicks off the sale of its Early Bird tickets today. The three-day passes are $175 and are offered at this price until they sell out; then, after that, tickets are $190. Although the complete lineup won't get its official announcement until April 21, Billboard's sources confirmed the headliners — Beastie Boys, Jane's Addiction, Depeche Mode, Tool, Kings of Leon and the Killers — as well as several other buzz acts: Fleet Foxes, Andrew Bird, Lou Reed, Neko Case, the Decemberists, and Peter, Bjorn and John. In an interview with MTV earlier this month, fest founder Perry Farrell claimed that the festival had also booked a "who's who" lineup of electronic music artists. Wonder how long before Lollapalooza will mimic big fests like Bonarroo, Coachella, and 10,000 Lakes, and offer a payment plan for its tickets?
