I don't know how many people on here are that familiar with Ryan Adams, but his output starting in 1995 with Whiskeytown is absolutely staggering:

Whiskeytown:
- Faithless Street (1995)
- Pneumonia (1997)
- Stranger's Almanac (1999/2001)

Solo:
- Heartbreaker (2000)
- Gold (2001)
- Demolition (2002)
- Rock N Roll (2003)
- Love Is Hell (2004)
- 29 (2005)
- Easy Tiger (2007)
- Orion (2010)

Ryan Adams & the Cardinals:
- Cold Roses (2005)
- Jacksonville City Nights (2005)
- Cardinology (2008)
- Cardinals III/IV (2010)

15 albums over that span, and very few missteps: all three Whiskeytown albums are great, same with the Cardinals recordings (though I haven't heard Cardinology), and his solo stuff has been excellent as well (Demolition is the worst, Rock N Roll is spotty, and I haven't heard Orion yet, to be fair).
