Though the Slackers are usually labeled in the ska genre, it's hard to say they perform one style of music - because they really don't.

They're reggae. They're soul. They're jazz.

In fact, it's probably why their fans find them so appealing - they can relate to the music because is covers genres across the board.

The Slackers are celebrating their 20th anniversary tour and they stop in Tucson on Wednesday for a show at 8 p.m.

Here's what Tucson Weekly's Stephen Seigel said about the band in 2009:

You've gotta hand it to The Slackers. As one of the first and best bands of the third wave of ska in the 1990s, they've outlasted and outclassed just about every other American ska act. Perhaps it's due to their versatility; rather than simply merging ska rhythms and horns with punk rock, as so many bands of the era did, The Slackers showed a bit more respect for ska's roots, drawing from reggae, soul, dub and jazz along the way. Hell, any ska band that covers a Nat Adderley tune on its first album is all right by me.
