Alexander Giannascoli (born 1993), better known by his stage name (Sandy) Alex G (formerly Alex G), is an American musician based in Philadelphia. He started his career with DIY self-releases on Bandcamp, and began building up an audience with his label debut, DSU (2014), released on Orchid Tapes to critical acclaim from various publications. He later signed with Lucky Number, who reissued his earlier releases, Rules and Trick (2012). In 2015, he signed with Domino Recording Company and released his sixth studio album, Beach Music. He followed it in 2017 with Rocket, which received further acclaim and recognition.
Giannascoli's music is often characterized as indie rock with a lo-fi or "bedroom pop" aesthetic, due to him recording all of his music by himself in his home. He is frequently compared to singer-songwriter Elliott Smith, who is an influence of his. Other comparisons include Built To Spill and The Martinis. The Philadelphia Inquirer praised him as "a particularly gifted melody writer" whose "fuzzy, sometimes distorted songs, which hark back to slightly askew 1990s bands such as Pavement, can't hide his skill as a pop craftsman and a constructor of elliptical narratives that call for repeated listening".
