Listening to Loose Ends on Radio 4 this afternoon brought to my attention the group, Portico Quartet, who has apparently been kicking around since 2005 (better late, etc. etc.). On today's programme they performed "Steepless" from their self-titled third album (2012). May have to invest more time in listening to these lads.
