Good stuff Max. Being older, I have migrated away from Rock towards other guitar-based musics, particularly Bluegrass. There are some great acoustic guitarists making music these days, as well as players of other string instruments. Any recording on which dobroist Jerry Douglas plays is fantastic, for instance. A benefit of music made on acoustic instruments is that there is often great harmony singing as well, a passion of mine.
The No Depression website is a great source for current guitar-centric music, where The Jayhawks and similar bands have long been covered.
