I've adjusted the format of the listings, hoping to make them less of a jumble, though they remain completely personal and arbitrary (I think the vogue word for that now is curated). There's a huge amount of really appealing stuff going on this month.
As mentioned last month, at Shotgun Players this month you can see Salvage, the third part of Stoppard's Coast of Utopia trilogy; you can also see the first two parts separately, or on two marathon days: 5 April and 26 April. For extra Russian thrills, on 15 April they present a staged reading of A Month in the Country by Turgenev, who is one of the characters in Stoppard's play.
Cutting Ball presents the American premiere of Communiqué No. 10 by Samuel Gallet, translated and directed by Cutting Ball Artistic Director Rob Melrose, 25 April to 25 May. Their Hidden Classics series has an interesting-looking offer on 27 April: Shakespeare's Venus and Adonis in a one-woman show with Ponder Goddard, directed by Melrose.
The Aurora Theater presents Wittenberg by David Davalos, directed by Josh Costello, in which Hamlet, back for the new school year (this must have been before his return to Wittenberg was ruled "most retrograde to [Claudius's] desire") has classes with Martin Luther and Dr Faustus. Sounds positively Stoppardesque, in case Coast of Utopia at Shotgun hasn't slaked your thirst. That's 4 April to 4 May. Also, on 17 April they are also opening a new, even more intimate performance space, Harry's Upstage, with The Letters by John W. Lowell, directed by Mark Jackson.
Philharmonia Baroque presents Vivaldi's oratorio, Juditha triumphans devicta Holofernis barbarie, conducted by Nicholas McGegan, with the Philharmonia orchestra and chorale joined by soprano Dominique Labelle and mezzo-sopranos Cécile van de Sant, Vivica Genaux, Diana Moore, and Virginia Warnken. That's 2 - 6 April in their usual varied locations.
American Bach Soloists explores J S Bach and his legacy in a concert featuring motets and choral works by Bach, Mendelssohn, Brahms, Sandström, and Nystedt. That's 25 - 28 April, in their usual various locations.
Cal Performances presents their resident new-music group, the Eco Ensemble, on 12 April, performing works by Gee, Harvey, and Lin. My thoughts on their last concert may be found here.
Cal Performances presents the Kronos Quartet in Beyond Zero: 1914 - 1918, a new work for quartet and film. As the dates might tell you, this work commemorates the centennial of the start of the first World War. The music is by Aleksandra Vrebalov and the film by Bill Morrison. That's 6 April.
The 2014 Switchboard Music Festival takes place Saturday, 12 April, from 2:00 to 10:00, at the Brava Theater in the Mission. More information here.
The San Francisco Conservatory of Music remembers composer and faculty member Conrad Susa, who died last November, with an evening of his music, held at St Mark's Lutheran Church in San Francisco. That's 5 April; more information here.
UPDATE: Thanks to Lisa Hirsch for pointing out (please see the comments) that this month also includes the San Francisco Contemporary Music Players festival of Electro-Acoustic Music, 24 - 27 April at Fort Mason. More information here. As I said to Lisa in reply to her comment, this is up against Opera Parallele's Weill/Poulenc double bill, and Mark Morris's world premiere production of Acis and Galatea, and American Bach Soloists, and Fort Mason has got to be one of the most difficult venues to get to in the Bay Area, so sadly this one is not happening for me. I used to get postcards and e-mails from SFCMP, but for some reason they stopped sending them, and though their programs always look interesting they persist in thinking that 8:00 PM is a good start time for concerts during the work week, which it is not for working people, so unfortunately I just don't think to check them much these days.
The San Francisco Conservatory of Music presents Dominick Argento's Postcard from Morocco, 10 - 13 April.
Opera Parallèle presents a double bill of Weill's Mahagonny Songspiel and Poulenc's Les Mamelles de Tirésias, conducted by Nicole Paiement and directed by Brian Staufenbiel, 25 - 27 April at the Yerba Buena Center. More information here.
San Francisco Performances presents bass-baritone Luca Pisaroni with pianist Wolfram Rieger, performing Beethoven, Reichardt, Brahms, and Liszt, on 1 April at the Nourse Theater.
San Francisco Performances presents pianist Marc-André Hamelin, clarinetist Martin Frost, and violinist Anthony Marwood, performing Schubert, Debussy, Stravinsky, Poulenc, and Bartok on 28 April at the Nourse Theater.
Cal Performances presents the return of the Mark Morris Dance Group in the world premiere of Morris's new production of Acis and Galatea. Handel's music as arranged by Mozart will be performed by Philharmonia Baroque. That's 25 - 27 April in Zellerbach Hall.
The San Francisco Ballet presents the west coast premiere of Alexei Ratmansky's Shostakovich Trilogy, 2 - 13 April; and the world premiere of Caprice, choreographed by Helgi Tomasson to Camille Saint-Saens, along with the twentieth anniversary presentation of the first work Mark Morris did for the company, Maelstrom, to music by Beethoven, along with Yuri Possokhov's version of Stravinsky's Rite of Spring, 4 - 15 April.
