Yup, Bach for sure. Several hundred, mostly on CD. Also Beethoven, Mozart, Vivaldi, Handel, Purcell, Rameau, Scarlatti, Couperin. Obviously, heavy on Baroque.
In Pop, Dylan (everything). Then Dave Edmunds (ditto), The Everly Brothers (no Everly Brothers = no The Beatles), The Louvin Brothers (no Louvin Brothers = no The Everly Brothers), Buddy Holly, Nick Lowe, The Band (no duh), The Beach Boys (those when Brian was a member), Van Dyke Parks, ABBA (go ahead, laugh. You’re mistaken ;-), The Kinks (whatta group!), The Flamin’ Groovies, The Ventures, John Hiatt, Lucinda Williams, Los Lobos, Richard Thompson, Iris Dement, Buddy Miller, Emmylou Harris, Patty Loveless, Steve Earle, Mary Gauthier, Rodney Crowell, Jim Lauderdale, Marshall Crenshaw, Hank Williams, George Jones, Del McCoury, all the regulars.
But some of my favorite music has been made by bands/groups/artists with a small discography. Rockpile (a single album, though the ensemble is heard on many of Edmunds’ and Lowe’s albums), The Notorious Cherry Bombs (a Rodney Crowell/Vince Gill side-project, with a single album). I could go on, but my glass is empty, and I’m low on Vodka. Gotta get to the liquor store.
