Markus Popp (aka Oval) has released a free 16 track album on which he performs with seven musicians and vocalists from Argentina, Brazil, Colombia, Uruguay and Venezuela.

Funded by the Goethe Institute, the album, Calidostópia! is the result of a ten day studio session in Brazil, and includes vocalists Agustín Albrieu (Argentina), Dandara Modesto (Brazil), Andrés Gualdrón (Columbia), Maité Gadea (Uruguay), Aiace Felix (Brazil), Hana Kobayashi (Venezuela) and Emilia Suto (Brazil).

Calidostópia! is available in FLAC or 320kbps MP3, and Popp says he plans to perform live with the project. More details here.

A secret history of music might be traced through the records that are left behind. As independent record shops and chain megastores alike close by the week, charity shops are filling some of the gaps left in the high street – what used to be damp caves of unwanted cha-cha and James Last chancers, are now key places to discover exotic and unheralded, lost and unlikely music.

Dedicated bargain hunter Ian Penman joins Derek Walmsley on Adventures In Sound And Music to discuss his best (and worst) scores in charity shops, boot sales and other gilded palaces of junk – from rare finds to illuminating quick buck compilations to long deleted numbers with a story to tell. This is the canon time (deliberately) forgot, a crate digging drift through the off key and unmourned, the plain daft, the sometimes strangely poignant; a cache of misplaced music ready to be found again.

This edition of Adventures In Sound And Music will be broadcast online and at 104.4 FM in London, on Resonance FM, on 28 March, 9pm–10:30pm.
