British rock vets Jethro Tull have announced 16 U.S. dates to honor the 40th anniversary of the classic 'Aqualung' release.

Speaking with journalist Peter Chakerian, Tull frontman Ian Anderson said that he wouldn't “rule out” the prospects of a new Jethro Tull album but “logistics” relating to the band members being spread out in different locations would make it difficult. Anderson said that it was likely that the band might opt to put out digital downloads initially, with the option of later bundling them into some sort of physical product.

Anderson also spoke about why he's more inclined to tour than record new material and said “at my age, touring seems more appealing than sitting in a room with no windows for three months. [laughs] I have to be realistic about these things because I’m not sure how much longer I have with good health and energy and ability to perform live. It could be one year or 10.”

The 'Aqualung' album features a number of tracks that have become Tull classics, including the title track, 'Locomotive Breath' and 'Hymn 43.' It was the first Top 10 album for the band, reaching No. 7 on the charts.
