At Your Service is the debut live album by the supergroup Sammy Hagar & The Circle, released on May 19, 2015, through Mailboat Records. Recorded during their 2014 tour, the album showcases a career-spanning setlist that Hagar famously dubbed a "four decades of rock" experience.

Sammy Hagar: Lead vocals and guitar.
Michael Anthony: Bass and backing vocals (Hagar's Van Halen bandmate).
Jason Bonham: Drums (son of John Bonham).
Vic Johnson: Lead guitar (from Hagar's band, The Waboritas).

Setlist Highlights
The album features 19 live tracks (16 on the DVD version) that mix Hagar’s solo work, his time with Montrose and Van Halen, and several Led Zeppelin classics as a nod to Bonham's heritage.
Van Halen Era: "Poundcake," "When It's Love," "Why Can't This Be Love," "Finish What Ya Started," "Best of Both Worlds," "Right Now," and "Dreams".
Led Zeppelin Covers: "Good Times Bad Times," "Whole Lotta Love," "When the Levee Breaks," and "Rock and Roll".
Solo & Montrose: "I Can't Drive 55," "Heavy Metal," "There's Only One Way To Rock," and "Rock Candy".
Waboritas/Solo Deep Cuts: "Little White Lie".

The release was available as a 2-CD set and later as a concert DVD in December 2015, which included behind-the-scenes footage and interviews. While it was the group's first release, they eventually followed it up with studio albums like Space Between (2019).
