After 40 years of leading Jethro Tull to 52 countries spanning several continents, Ian Anderson brings his new acoustic tour to old and new friends alike. With a band consisting of German guitar virtuoso Florian Opahle, pianist and accordionist John O'Hara, bassist David Goodier, and special guest violist Meena Bhasin, Ian will play Tull acoustic classics as well as other specially-rearranged Tull rock material and, in addition, some new material specially written for these tours. Drawing on Folk, Classical, Rock and Jazz music styles, Ian blends elements of many world music cultures to delight his fans.

The tour schedule can be found here.

From official Gentle Giant website:

Three Friends is a band starring several former members of Gentle Giant: Gary Green (guitar, vocals), Malcolm Mortimore (drums), Kerry Minnear (keyboards) plus: Roger Carey (bass and vocals, from Liane Carroll's band), John Donaldson (piano and keyboards), Andy Williams (guitar, collaborator with Carey in the Engine Clutch And Gearbox trio), Mick Wilson (vocals, from 10cc). The band plays Gentle Giant songs and plans to create original music. This is not a Gentle Giant reunion. It's a new band.
