Which artists' music do you buy without audition

We all have our favorite artists and often have large collections of music by them. Name some who when a new cd or vinyl comes out you will buy without hesitation, audition or others' opinions.

Emmylou Harris is one of those for me.
- Chet Atkins, Johnny Cash
- Moody Blues, Savoy Brown, Ten Years After/Alvin Lee, Porcupine Tree, Motorhead, AC/DC
- Cusco, Patrick O'Hearn
- Robert Johnson, Muddy Waters, John Lee Hooker, Guitar Shorty
- Ella Fitzgerald, Louis Armstrong, Duke Ellington, Sophie Milman, Lou Donaldson
- Bach, Beethoven, Mahler, Schumann, Shostokovitch, Rachmaninoff, Sibelius, Prokofiev, Villa Lobos
- John Barry, Ennio Morricone, Arthur Fiedler

Also I will buy many a compilation album without audition to help fill in my music library with good stuff from various one off acts.
Herbie Hancock, Murray Perahia, Bill Frissel, Guidon Kremer, Wayne Shorter.
