In May 1966, the Rolling Stones issued the raga rock single "Paint It Black", which featured a sitar part played by guitarist Brian Jones and became an international number 1 hit. According to author Mark Brend, the song "spawned a whole subgenre of minor-key psychedelia". The Hollies' "Bus Stop", released as a single in June, was another example of the style's growing popularity. Echard identifies the song's sitar-like guitar solo as both an authentic indicator of raga rock and a device seemingly aimed at exploiting the trend.
