For those of you who are not familiar with Dispatch, trust us: Their worldwide fans are very excited right now. When they went on an “indefinite hiatus” in 2002, they announced a final show at the Hatch Shell in Boston. They didn’t know who would show. What they got was 110,000 fans from 25 countries.

When they announced a reunion show (to draw attention to the plights of Zimbabwe) in 2007, they picked Madison Square Garden. So many people wanted to see them that they played three sold-out evenings – an unprecedented feat for an indie band.

Now they’re touring, beginning with the famed Red Rocks Amphitheatre near Denver June 4. They’re also going to be the first band to play Red Bull Arena, the 25,000-capacity MLS field in Harrison, N.J. (which is just a quick jaunt from Manhattan).

Other dates on the books are Jay Pritzker Pavilion in Chicago June 8, Greek Theatre in Berkeley Calif., June 11, Chastain Park Amphitheatre in Atlanta June 21 and TD Garden in Boston June 25.

Pre-sale tickets will be available Jan. 21 and to the general public Jan. 28 at

Now for the skinny: Dispatch is composed of Brad Corrigan, Pete Helmbold and Chad Urmston. They had a rather unassuming career as Dispatch from 1996 to 2002 and one notable single called “The General.”

But from 1999 to 2001 there was this peer-to-peer program called Napster, and its creator, Shawn Fanning, was a big Dispatch fan. The band, accustomed to the usual touring in a van, became a song-trading phenomenon, a la O.A.R. When they said goodbye in 2002, every one of the 110k people near that bandshell knew every lyric to every song.

By the way, the last time this writer talked about Dispatch in Jan. 2007, he got savaged by none other than online notable Maura Johnston because I didn’t define their music genre. Worse, I was dubbed – ugh – a “music journalist.” Talk about low blows.

But I was oh so young back then. This time I know better: Dispatch kind of has a Sublime / jam-band / Jack Johnson flair. Phew. I feel a lot better. The “music journalist” thing still stings though.
