There are thousands of them,
@Lullabelle - almost everything I've listened to since the late 1950s has impacted my life in one way or another. If I tried to list everything I'd crash the website.
One guy I listen to a lot is Aaron Burdett from Saluda, NC. Probably unknown outside NC (and probably largely unknown inside NC too), Aaron has put together a handful of CDs over the last 10 years that all stand up to repeated listening. His music is often described as Americana (a term I dislike) - a
mélange of musical styles which have their 'origins' in the US : country, bluegrass, rock etc. He writes thoughtful and sometimes whimsical songs, largely reflective of the daily grind. He deserves to be much better known.
Another CD that I've been listening to a lot in October is Bobby Watson's 'Appointment In Milano'. Fairly straightahead post-bop, Bobby's backed by three Italian jazz musicians - Piero Bassini on piano, Attilio Zanchi on bass and Giampiero Prima on drums. Recorded in Milan in 1985 and still sounding fresh 30-odd years later.
I'm not much of a fan of jazz fusion but I've enjoyed listening to Per Mathison's 'Sound Of 3' recording from 2016 this week. I didn't think I'd ever get excited about Norwegian jazz fusion, but this is good stuff.
As these three CDs (alongside dozens of others this month) have influenced the way I feel, then they could be said to have impacted my life. And anyway I wanted to be the first (and undoubtedly the only) person to mention Aaron Burdett on the forum.
