Bob Weir's Ratdog [ tickets ] has laid down plans for a spring tour, and added a Valentine's Day date in San Francisco to its already announced itinerary.

The group, led by former Grateful Dead singer/guitarist Bob Weir, is scheduled to hit the road Feb. 9 in San Diego and play through late March. The first half of the band's schedule features West Coast appearances, while the latter portions skews heavily toward Northeastern shows, including a three-night stand at New York's Beacon Theatre beginning March 8.

Weir formed Ratdog--originally known as RatDog Revue--in 1995 with bassist Rob Wasserman, who is no longer involved with the group. The band unexpectedly became Weir's primary musical vehicle following the death of Grateful Dead co-founder Jerry Garcia in 1995.

Though Ratdog has always been a strong draw on the concert circuit, the group's only studio album is "Evening Moods," released by Arista Records in 2000.

Joining Weir in Ratdog's current lineup are drummer Jay Layne, keyboardist Jeff Chimenti, guitarist Mark Karan, saxophonist Kenny Brooks and bassist Robin Sylvester.
