With the all-star Down From the Mountain tour recently finished, Alison Krauss & Union Station are looking ahead at a busy spring. The group will maintain a high media profile in advance of its upcoming tour in support of its latest album, "New Favorite" (Rounder).

The 15-date trek kicks off March 21 in Detroit and wraps April 27 with an appearance at the annual Merle Watson Festival ("Merlefest") in Wilkesboro, N.C. Also on the itinerary is a performance Saturday (Feb. 23) at Texas' annual RodeoHouston event with Down From the Mountain tour mates Emmylou Harris and Patty Loveless, as well as Nickel Creek.

As previously reported, Krauss and her band will take part in a performance of songs from Mercury's "O Brother, Where Art Thou?" soundtrack during Wednesday's (Feb. 27) Grammy Awards ceremony. Krauss will join Harris and Gillian Welch for a rendition of "Didn't Leave Nobody But the Baby," while Dan Tyminski will lead the band through a rendition of "I Am a Man of Constant Sorrow." Both songs are nominated for the best country collaboration with vocals Grammy.

The "O Brother" set, which featured Krauss & Union Station among a cast of bluegrass and American roots music greats that included Ralph Stanley, is up for the album of the year Grammy. Stanley's version of "O Death" is up for best male country vocal performance. In addition, the "New Favorite" track "The Lucky One" is up for best country performance by a duo or group with vocal.

Following the Grammy appearance, Krauss & Union Station will on March 1 perform abridged versions of "Down to the River To Pray" and "I Am a Man of Constant Sorrow" on NBC's "The Tonight Show With Jay Leno." Appearances on a CBS "Sunday Morning" bluegrass special and PBS' "Austin's City Limits" are also in the offing, as is a feature Monday (Feb. 25) on the cable Oxygen network's "Daily Remix."

Released last August, "New Favorite" debuted at No. 3 on Billboard's Top Country Albums chart and No. 35 on The Billboard 200.
