HAYNES HAS HIS HANDS FULL (SO WHAT ELSE IS NEW?)

There really is no such thing as downtime for guitarist Warren Haynes.

His main gigs are playing with the Allman Brothers Band and Gov't Mule, and that would be enough for most musicians to handle. But he's added to his workload with the relaunch of his Evil Teen record label.

On Wednesday (March 28), which was a night off from the annual Allman Brothers Band residency at New York's Beacon Theatre, Haynes publicly celebrated Evil Teen's return with a star-studded show at Irving Plaza. The performers that night included Gregg Allman, Edwin McCain and Kevn Kinney.

Haynes and the aforementioned musicians are featured on The Benefit Concert: Volume 2. Recorded in 2000, the two-disc set is the first Evil Teen release under its new distribution deal with RED. The Benefit Concert: Volume 1, recorded in 1999 and originally issued as Wintertime Blues, will be released Tuesday (April 3), featuring performances by Gov't Mule, Susan Tedeschi, The Derek Trucks Band and others.

SO LONG, SIN-E; HELLO FILLMORE

As one Manhattan concert venue gets set to close, another is about to have a new name and look.

Sin-e, perhaps best known as the place where the late Jeff Buckley honed his chops, will present its final show Sunday (April 1) -- and no, this is not an April Fools' Day joke.

The club opened in 1989 on St. Marks Place; the current Sin-E, at 150 Attorney St., opened in 2001. Its final bill features Hymns, Bow Thayer & the Perfect Train Wreck and Amanda Kravat.

Doors open at 8 p.m. Sunday; the show starts at 9 p.m. Cover charge is $10 in advance and $12 at the door. Visit www.sin-e.com for more information.

Meanwhile, Live Nation is sprucing up Irving Plaza, which will open as Fillmore New York at Irving Plaza on April 11 with a show starring British upstart Lily Allen.

It's part of Live Nation's plan to establish a brand a la its House of Blues clubs across the country. Currently, there are Fillmore facilities in San Francisco and Denver. A Philadelphia Fillmore is scheduled to open in late April.

On April 11 at Irving Plaza, fans can expect to find repainted walls, refurbished chandeliers and better sightlines from the balcony area. Bathroom, sound and lighting upgrades are scheduled for the summer.

How these upgrades impact ticket prices remains to be seen.
