Saw them last night in Huntsville playing Led Zeppelin's "Houses of the Holy." For those unfamiliar, they recruit various musicians that sound like the original artist and play all of the songs on the record, trying to recreate the original as much as possible. They then played other Led Zep tunes afterwards (Kashmir was awesome). They have done Dark Side of the Moon and Hotel California as well. Great show to see if you get the chance. Prince's "Purple Rain" is next for them in May.
