The concert by Skid Row occurs following a European circuit by the band promoting their "United World Rebellion Tour."

Skid Row is an American heavy metal band, formed in 1986 in Toms River, New Jersey. They were very successful in the late 1980s and early 1990s, with their first three multi-platinum albums.

To date, Skid Row has released five full-length albums, an EP, a compilation album, and a live album.

Rockapella has become one of the world's most sophisticated and lasting pop vocal groups. With the wild success of the TV smash "Glee" and a cappella groups reigning in the Corner of Cool on college campuses, there is increased demand for live vocal performance.

A single concert opens a window on practically the whole history of vocal music from vintage Mills Brothers through jazz and rock to current Hip Hop.

The little miracle that keeps the crowds coming back year after year and constantly draws new fans is Rockapella's astonishing full-band sound. A sound that seems to be impossible coming from just five guys with microphones. No instruments, no tracks, no mirrors – and their hands never leave their wrists. "We're making every bit as much music as the whole 'Glee' chorus – but with only five guys," says Rockapella's human beat-box Jeff Thacher.

Lightfoot had many major hits including "If You Could Read My Mind," "Sundown," "Rainy Day People," and "The Wreck of the Edmund Fitzgerald."

He has played with some of his band members for more than 40 years.

His music was discovered in 1964, when he was performing on the Toronto folk scene; Fellow Canadians Ian and Sylvia chose two of his songs, "Early Mornin' Rain" and "For Lovin' Me" for their next record, aptly named for the first song.

He achieved international success in folk, folk-rock, and country music, and has been credited for helping define the folk-pop sound of the 1960s and 1970s. He has been referred to as Canada's greatest songwriter and internationally as a folk-rock legend.
