Whistler was an obscure and forgotten progressive folk-rock band from England who released just a single album in 1971 on the progressive Decca sub-label Deram. George Howe (keyb, g, voc), John Chuter (g, b, voc) and Anthony Grout-Smith (keyb, g, b, sax, voc), who also created the cover illustration, played a melodic, gentle rock that spanned a spectrum from folk to progressive and pop. During the recording sessions at Decca Studios in March 1971, they were supported by the crème de la crème of the British studio scene. The twelve gently and carefully orchestrated tracks were supported by a sensitive and rich-sounding production by Peter Johnson.

But none of this could prevent the band and their sole album from disappearing into obscurity. Today, the album Ho-Hum ranks among the most sought-after rarities on the British Deram label and is particularly highly sought after by Asian collectors. As a test pressing, there are probably only a few copies in existence worldwide.
