He also inaugurated an important series of recordings of neglected masterpieces with the Telarc label, using the ASO and a variety of European orchestras. In addition to his work with the ASO and JSO, Botstein has performed as a guest conductor with, among many others, the London Philharmonic Orchestra, New York City Opera, Los Angeles Philharmonic, BBC Symphony Orchestra, London Symphony Orchestra, St. Petersburg Philharmonic Orchestra, and NDR Symphony Orchestra. The Los Angeles Times called 2013's Los Angeles Philharmonic performance under Botstein "the all-around most compelling performance of anything I've heard all summer at the Bowl."[9] In fall 2013, Botstein also conducted the Sinfónica Juvenil de Caracas in Venezuela and Japan, making him the first non-Venezuelan conductor invited by El Sistema to conduct on a tour.[10] Many live recordings of his performances, including the prestigious operas performed every summer during the Bard SummerScape festival, are widely available on compact disc and on Internet sites such as iTunes, Amazon, and Spotify.
