Brooks & Dunn, Willie Nelson, and Alan Jackson are among those paying tribute to long-haired Texas trio ZZ Top on the upcoming RCA album "Sharp Dressed Men," a 15-track country homage to the veteran group. Set for an April 30 release, the 67-minute album also features contributions from such honky-tonkers as Trace Adkins, Tracy Byrd, and Dwight Yoakam.

The album includes Brooks & Dunn's take on "Rough Boy," while Adkins tackles the pool-hall staple "Legs," which, at No. 8, is ZZ Top's highest-charting single on The Billboard Hot 100. Country man of the moment Jackson handles "Sure Got Cold After the Rain Fell" from ZZ Top's 1972 sophomore effort, "Rio Grande Mud." A spokesperson says the label has yet to pick a single.

ZZ Top is currently at work on a new album, which the spokesperson says is due for an October release. The band has scored six top-10 albums, with 1985's "Afterburner" reaching a high of No. 4. The band's breakthrough came with 1983's "Eliminator," which contained "Legs" and "Sharp Dressed Man," the latter of which is covered here by Brad Paisley.

To hype the album, ZZ Top has taped an episode of CMT's "Crossroads," which features a handful of collaborations with Brooks & Dunn. The show debuts on CMT April 21 at 8 p.m. EST.
