Here is a list of all pieces in The Works project that are for one or more string instrument soloists (other than violin only) with orchestra. The list is arranged roughly chronologically. 

If the work doesn't have a title beyond “X Concerto” or “Concerto for X and Orchestra”, then only the composer's name is mentioned (see Walton under viola for an example). If the composer has more than one such concerto, the number or numbers are listed (see Haydn under cello for an example).

Week 3 of The Works begins with the new podcast episode, in which I review last week's pieces, share a little bit about my experience with opera as a non-opera-buff, and preview the works coming up this week.

Here is the Spotify playlist containing the recordings for Week 3.

Here are pieces on this week's list, including some links to the scores where available:

Giovanni Pierluigi da Palestrina
Missa Papae Marcelli
Missa Inviolata - this video is the only performance I could find.

Franz Liszt
Transcendental Études

Aaron Copland
Dance Symphony
Short Symphony

Giuseppe Verdi
Rigoletto - here is the libretto with an English translation, and here is a synopsis of the opera.

Week 2 of The Works begins with the new podcast episode, in which I review last week's pieces, discuss Bill and Ted's Excellent Adventure, and preview the works coming up this week.

Here is the Spotify playlist containing the recordings for Week 2.

Here are pieces on this week's list, including some links to the scores where available:

György Ligeti
Cello Concerto

Franz Schubert
Die Schöne Müllerin (find the song texts and translations here)

Agustín Barrios
Guitar Works (see Spotify playlist for specific pieces)

Wolfgang Amadeus Mozart
Piano Concerto No. 9

Big Joe Turner
This link shows the compilation album Big, Bad, and Blue as a 3-CD set with 61 tracks, but on Spotify it only has 28 tracks, so I have included all of those plus 6 more of his most important singles.

Eubie Blake
This link shows an LP of piano rolls made from Blake's playing between 1917-1921, recorded in 1973 under Blake's supervision. My Spotify list includes all of these songs, but I can't be sure they're the same recordings. A few other Blake pieces, played by himself, are also on the list. Most of his scores are not yet public domain, but this one is (in the US only).

Other Ragtime Composers
James Scott: Grace and Beauty and Ragtime Oriole
Tom Turpin: Saint Louis Rag
Joseph Lamb: American Beauty and Nightingale Rag
