Fleetwood Mac have almost finished eight songs for a possible new album.
The new recordings feature Christine McVie, who announced she was rejoining the band in January, although Stevie Nicks has so far been absent from recording sessions due to other commitments.
The band's guitarist Lindsey Buckingham said in a recent interview: "The chemistry was just unbelievable. We're all very excited about the new music. Knowing me I'm going to be pushing hard for a double album."
Minus Nicks, Fleetwood Mac spent two months at Village Recorder studio in Los Angeles, working in the same room in which they recorded their 1979 album Tusk.
Despite the eight tracks being "75 per cent done," the sessions will be put on hold as McVie returns to the UK where she lives.
The band are scheduled to begin rehearsals for their world tour in July, meaning it’s unlikely a new album will be released before 2015. Titles for the new tunes include "Carnival Begin" and "Red Sun."
"Fleetwood Mac always take a long time to make a record," McVie said. "Obviously, there are parts for Stevie to sing on all of these songs, which she will do eventually."
McVie is working with Fleetwood Mac for the first time since 1995, and says she has no plans to leave. The band released an EP in 2013, called Extended Play, which only reached only No 125 on the UK album chart.
