Trees was a British folk rock band recording and touring throughout 1969, 1970 and 1971, reforming briefly to continue performing throughout 1972. Although the group met with little commercial success in their time, the reputation of the band has grown over the years, and underwent a renaissance in 2007 following Gnarls Barkley's sampling of the track "Geordie" on the title track of their multi-million selling album St. Elsewhere.

St. Elsewhere is the debut album by American soul duo Gnarls Barkley. It was released on April 24, 2006, in the United Kingdom, where it debuted at number one on the UK Albums Chart, and on May 9, 2006, in the United States, although it was available for purchase one week earlier as a digital download in the US iTunes Store. St. Elsewhere debuted at No. 20 on the US Billboard 200, and peaked at No. 4. It topped the Billboard Dance/Electronic Albums chart for 39 non-consecutive weeks in 2006 and 2007.
