Brad Paisley's newest record, This is Country Music, plays like a country rock mix tape curated and orchestrated by Paisley himself. It's packed with guest appearances from the likes of coiffed guitar acrobat Marty Stuart, classic rock crooner Don Henley and, of course, Paisley's go-to duet partner these days, Carrie Underwood. Plus, Clint Eastwood whistles the melody to the instrumental 'Eastwood.' If that sounds like the most awesome thing ever, well, what can we say?

Not that it's anything new for the 'Celebrity' singer - he's put together some great collaborations in his day. Check out our list of the five best Paisley duets of all time.

'Old Alabama' with Alabama (2011)

Paisley's newest single from This is Country Music is a stomping tribute to the music of Alabama, featuring the country rock legends themselves.

'Start a Band' with Keith Urban (2009)

Two of country's best singers/ax-slingers trade versus and licks in Paisley and Keith Urban's ode to that great American tradition of "finding a few good buddies and starting a band."

'Whiskey Lullaby' with Allison Krauss (2004)

'Whiskey Lullaby,' a lament for a couple whose lives are torn apart by alcohol and infidelity, features the voices of Paisley and Allison Krauss intertwined over a dirge of dobro and acoustic guitar.

'When I Get Where I'm Going' with Dolly Parton (2006)

Paisley's stoic lyrical confrontation with death is sweetened by Dolly Parton's contribution to this hit off 2005's Time Well Wasted.

'Louisiana Woman, Mississippi Man' with Carrie Underwood (2009

'Oh Love' was the Paisley-Underwood duet that won Paisley a Grammy nomination in 2008. But this awesomely-awkward television performance of the Conway Twitty/Loretta Lynn classic 'Louisiana Woman, Mississippi Man' is our pick for the best collab between Paisley and 2005 American Idol winner.
