In September, Wilco frontman Jeff Tweedy and his 18-year-old son Spencer released an excellent double LP, Sukierae, under the name Tweedy. They recently sat down with EW editor Matt Bean to discuss the record for SiriusXM Artist Confidential on Entertainment Weekly Radio.

“It’s really two short records, and we sequenced two records,” Jeff said of the project, which was actually culled from 40 demos. To make “a complete picture,” Tweedy released the two albums together, rather than releasing them six months apart and losing that interplay.

The Tweedys also explain how wife/mother Susie’s battle with cancer inspired the record’s title and lyrics. “You feel more comfortable doing that when you don’t have a collective that you’re representing,” Spencer said. “In Wilco it’s a group of people and it doesn’t feel appropriate sometimes to get in depth like that.”

The entire interview will air at 7 p.m. ET tonight and across the weekend on SiriusXM channel 105.
