Steve Earle and the Del McCoury Band only made one album together – The Mountain (1999). It’s a great album. Instead of recycling bluegrass standards, they recorded an album of all new Earle songs. Apparently, there was a conflict and they did not record again. See #18 in this interview with McCoury. There are bootlegs of concerts in Oslo,Norway and Malmo, Sweden with great performances. The Mountain was proceeded by one song together (“I Still Carry You Around”) on 1997’s El Corazon.
