In 1951, Williams was one of the biggest stars in country music. He was also a pitchman for Mother's Best flour and farm feed, a company that sponsored a daily 15-minute radio show.

Plant's new solo album is called Band of Joy. That's the name of a group he was in back in 1967, before Led Zeppelin, with drummer John Bonham. Rock critic Ken Tucker says that if the album title suggests nostalgia for older musical styles, there's nothing musty about the results.

Skaggs became a mainstream country music star in the 1980s, but in recent years, he's become more interested in performing in a traditional bluegrass style. Ken Tucker says the tracks on Skaggs' album Mosaic "don't just fit together -- they lock into place with a firmness."

Arcade Fire is a Montreal-based band that has, in less than a decade, grown in popularity from obscure indie favorite to mass-appeal group that can fill New York's Madison Square Garden. Critic Ken Tucker says the band's third album, The Suburbs, has the sweep and ambition of a rock opera.

Los Lobos has been active since the 1970s, and during that time the band has done everything from opening for Bob Dylan, U2 and the Grateful Dead, to recording a tribute album to Walt Disney soundtracks. Rock critic Ken Tucker says Los Lobos' new album, Tin Can Trust, stands with the group's best work.
