Ben Thomas is a guitarist who frequently tours with Adele. Adele has referred to Ben as one of her best friends on several occasions. She has brought him to most of the venues she has played at. Thomas and Adele attended the BRIT School together.
Adele took him with her to meet with XL Recordings when she was first signed because she wasn't sure if they were a reliable record label.
Thomas is one of only two members of Adele's band to be with her during all three of her headlining tours, the other being drummer Derrick Wright.
While Adele was on hiatus working on her album 25, Thomas toured with British singer-songwriter Sam Smith. He has also recorded solo music when not touring with other artists.
