Tweaks to BBC 6 Music's Sunday schedule will be introduced on Easter Sunday, and include a new two hour show with Cerys Matthews.
Cery replaces Jon Richardson in the 10am till 12pm slot, whilst other programmes are either extended, reduced or moved to another day.
Adam Buxton, one half of 6 Music's Adam and Joe, also starts a new show on Easter Sunday. Adam Buxton's Big Mix Tape will take a weekly topic or theme and makes a compilation tape for listeners to share.
Adam's first guest on the inaugural show from 12pm till 2pm will be the Mighty Boosh's Julian Barratt.
Later, the Huey Show gains half an hour between 2 and 6pm, and Jarvis Cocker's Sunday Service moves half an hour later to the 4 till 6 slot. Stuart Maconie's Freak Zone follows, but is cut by half an hour between 6 and 8, whilst the new hour-long Freakier Zone will be broadcast on Friday nights at midnight.
6 Mix will air from 8pm till 10pm, with Dave Pearce's Dance Anthems moving from Sunday evening to the Saturday 10pm till midnight slot.
The now-two-hour long Finest Hour will then air from 10pm.
Bob Shennan, Controller, Radio 2 and 6 Music, says: "The new Sunday schedule offers a unique line-up of trusted guides to shine a light on hidden corners of the music world.
"With the addition of Cerys Matthews, Adam Buxton and the 6 Mix, 6 Music now promises to offer a distinctive day of eclectic music, presented by incredibly passionate and knowledgeable people, that I'm sure the listeners will enjoy."
The BBC Trust is currently holding a 12-week consultation on proposals to close the station, along with the Asian Network.
