Focus - At The Rainbow (1973) (K2HD)

The instrumental rockers of the early '70s never were any good at dulling down their musical expertise; and, indeed, it's only a matter of seconds into their first and only live release -- Live at the Rainbow -- until one realizes just how talented Focus were. Jan Akkerman, named "World's Best Guitarist" by Melody Maker in 1973 ahead of Eric Clapton and others, was amazingly on form in this performance. Thijs Van Leer, chief songwriter and performer in the band, showcased his talents on flute, vocals, and organ with unparalleled finesse.
